Re: TypeError: list indices must be integers, not tuple
Hi,
There is a lot of issues with this code. First, setting fav to a 1 tuples
with a string probably isn't what you want. What you probably mean is:
if restraunt == ("Pizza"):
fav = 1
Second, when you are trying to lookup items in Menu, you are using the
incorrect fav. Lists have int indicies (just like the error points out).
Values like ("1") aren't integers.
Thirdly, Menu is a list of lists. To fetch "Barbeque pizza" from Menu, you
need to do Menu[0][0], not Menu[0, 0].
Finally, Python comes with a style guide which you can find in pep8

If Node is an extension class written in C, it could do almost anything. It certainly doesn't need to follow Python conventions for Python classes. If this were a pure-Python class, I can think of at least three ways to get this behaviour: - use __slots__ so that the class has a fixed set of members with no __dict__ used or needed; - use a custom descriptor - use a custom metaclass that changes the behaviour of lookups; I presume that extension classes written in C can do similar things. > My understanding is the foobar is stored in n.__dict__, but seemingly n > has no __dict__. > > So where does the foobar go?

IIRC the docs also warn that mixing file iteration with other file

That's not a one-tuple (as in, a tuple with one element), it's a
two-element tuple. The point is that ("3") doesn't create a tuple,
it's just superfluous parentheses.

Here's the code I used for the Monopoly calculations.
import numpy as np
def monopoly(samples):
# 2d6 x 3
num = 2
sides = 6
rolls = 3
dice = np.random.randint(1, sides + 1, size=(samples, rolls, num))
# Doubles are if the two dice are the same
doubles = dice[...,0] == dice[...,1]
# Reroll if this (and all previous rolls) are doubles
reroll = np.logical_and.accumulate(doubles, axis=1)
# Keep the first entry, and any valid rerolls
keep = np.insert(reroll, 0, True, axis=1)
# The last column (all 3 are doubles) is "go to gaol"
keep, gaol = np.split(keep, [-1], axis=-1)
gaol = gaol[...,0]
# Add up all the rolls and zero out any we don't want to keep
totals = dice.sum(axis=-1) * keep
# Remove any "go to gaol" cases
totals = totals[~gaol,...]
# Add up the distance moved
totals = totals.sum(axis=-1)
gaol_count = np.sum(gaol)
return totals, gaol_count
samples = 100
totals, gaol_count = monopoly(samples)
print("Average distance moved =", totals.mean())
print("Percentage of times you go to gaol: {:%}".format(gaol_count/samples))
for i, count in enumerate(np.bincount(totals)):
print("{:>2} {}".format(i, count))
The actual calculations are fairly simple, once you get your head round the
tricks you need to do everything array-based. The part I find the hardest by
far, is keeping track of the dimensions of the arrays involved, and what I need
to do to match up axes, etc. For example, it took me a long time to work out
what was going wrong with stripping out the "go to gaol" cases. The problem
turned out to be that I needed the line "gaol = gaol[...,0]" to strip off a
dimension - but it was really hard working out what was going on, particularly
as numpy broadcasts the values you have, so you don't get errors, just weirdly
wrong answers. (This isn't unique to numpy, I remember having the same issues
when I used to work with J).
One thing it'd be nice to do would be to abstract out the array dimension for
the number of samples, so that the "application" code could be written as if
working on just one sample, and the driver code extended that to multiple
samples. But I don't have the first idea how I'd do that without ending up
looping in Python, which is what I need to avoid if I want performance to
remain good.
Lots of scope for more things to learn here, then :-)
Thanks again to everyone that helped.

You're right of course. I didn't notice the meaning of one-tuple; I took

The original error message said there was a tuple; I knew that fav
wasn't the tuple, but the combination of fav and RandomNum was.

Depends on what the expected behavior is -- is every grid position something that should be included in the iteration, or are we looking at elements of a container where some possible locations may be empty?

That is basically my thought as well. It would be possible to seek
around the file while iterating (seek to the current iteration
position, read, then seek back to the previous location), however that
would slow down iteration for little practical gain. It would also
require locking and possibly introduce odd corner cases.

So it explicitly states that seek, the method I used, should work
fine. I could not find any similar text in the 3.4 docs.

Taming the verbosity of ipython tracebacks
Hi folks, I'm running Python 3.4.0, and ipython3 1.2.1, on Ubuntu Linux 14.04 64-bit. Whenever I execute code from within ipython which triggers an exception -- any exception -- I get a page full of information. The exceptions in my code trigger exceptions within ipython. Every error message looks like this: ERROR: Internal Python error in the inspect module. Below is the traceback from this internal error. Traceback (most recent call last): File "/usr/lib/python3/dist-packages/IPython/core/interactiveshell.py", line 2821, in run_code exec(code_obj, self.user_global_ns, self.user_ns) File "", line 1, in << MY ERRONEOUS CODE, AND THE EXCEPTION IT GENERATED, ARE PRINTED HERE >> During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/IPython/core/interactiveshell.py", line 1713, in showtraceback stb = value._render_traceback_() AttributeError: 'NameError' object has no attribute '_render_traceback_' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/IPython/core/ultratb.py", line 759, in structured_traceback records = _fixed_getinnerframes(etb, context, tb_offset) File "/usr/lib/python3/dist-packages/IPython/core/ultratb.py", line 242, in _fixed_getinnerframes records = fix_frame_records_filenames(inspect.getinnerframes(etb, context)) File "/usr/lib/python3.4/inspect.py", line 1332, in getinnerframes framelist.append((tb.tb_frame,) + getframeinfo(tb, context)) File "/usr/lib/python3.4/inspect.py", line 1292, in getframeinfo filename = getsourcefile(frame) or getfile(frame) File "/usr/lib/python3.4/inspect.py", line 583, in getsourcefile if getattr(getmodule(object, filename), '__loader__', None) is not None: File "/usr/lib/python3.4/inspect.py", line 629, in getmodule os.path.realpath(f)] = module.__name__ AttributeError: 'FakeModule' object has no attribute '__name__' Unfortunately, your original traceback can not be constructed. When I run the same script directly from the Linux shell, I get a tidy traceback which tells me exactly what I want, and nothing more. But then, obviously, I lose the interactive ipython shell's capabilities. I would like to get rid of all that fluff surrounding my ipython error message. I'm not sure what the purpose of the inspect module is, or what FakeModule is. I wonder whether I have failed to install something correctly.

I now have ipython 2.4.1 as well, and my tracebacks are behaving. Ubuntu's repository apparently has an outdated version of ipython. Also, a heads-up: the pip3 utility does not recognize a package named ipython3, the name that Ubuntu expects. The package name reverts to plain-old ipython. This name conflict might cause problems for someone who wants to run ipython with Py2 -- while that isn't me, it may affect some of you. -- https://mail.python.org/mailman/listinfo/python-list

Wildly OT: pop-up virtual keyboard for Mac or Linux?
I know this is way off-topic for this group, but I figured if anyone in the online virtual communities I participate in would know the answer, the Pythonistas would... Google has so far not been my friend in this realm. One of the things I really like about my Skype keyboard (and likely other "soft" keyboards on Android) is that when you hold down a "key" for a brief moment, a little mini keyboard pops up, from which you can easily choose various accented variants and other symbols. For instance, If I press and hold the "d" key, I see these choices (ignore the capitalization of the first letter - my mistake sending a text message to myself from my phone, and I can't seem to convert it to lower case): Đ|¦&dðď While I'm a touch typist, I almost never use auto-repeat, which is the "binding" of held keys in most environments (curse you, IBM and your Selectric!). These days I find my self needing accented characters much more frequently than key repeat (C-u 2 5 - suffices in Emacs to bat out 25 hyphens). Being an American with an American keyboard, I haven't the slightest idea how to type any accented characters or common symbols using the many modifier keys on my keyboard, and no key caps display what the various options are. And I'm getting kind of tired of going to Google and searching for "degree symbol". :-/ Is there an X11 or Mac extension/program/app/magic thing which I can install in either environment to get this kind of functionality? I'm thinking that if you hold down a key for the auto-repeat interval, instead of the key repeat thing making all sorts of duplicates, a little window would pop up over/near the insertion point, which I can navigate with the arrow keys, then hit RET to accept or ESC (or similar) to cancel. It need not be perfect. It might (for example) only work in certain environments (Chrome, Emacs, vim, Firefox). Anyplace to start. It need even be written in Python (though that would be cool.)

While it's not exactly a hold-down-get-a-menu, I opt for changing my (otherwise-useless) caps-lock key to an X compose key: $ setxkbmap -option compose:caps I can then hit caps-lock followed by what are generally intuitive sequences. For your first one, that would be "capital-D minus". I'm not sure what the other characters are supposed to be, so I'm not sure how to find them. But é is "compose, e, apostrophe", ñ is "compose, n, tilde", the degree sign is "compose, o, o", the € is "compose, E, equals", etc. There are loads of these documented in (on my machine, where my locale is en_US.UTF-8) /usr/share/X11/locale/en_US.UTF-8/Compose Some of them are a little less intuitive, though the majority of the time I can just guess them (I'd never typed "Đ" before, but guessed and was right). Otherwise I search that above file. This also has the advantage that it should work in every X application, including Unicode-aware terminal applications (in Unicode-aware terminals). Adding some sort of press-and-hold UI would limit it to those applications that chose to support it (or even *could* support it). > While I'm a touch typist, I almost never use auto-repeat, which is > the "binding" of held keys in most environments I agree, as vi/vim makes it easy to insert multiples of the same character (or characters) akin to what you describe in Emacs. -tkc -- https://mail.python.org/mailman/listinfo/python-list

That looks a lot more general than what I use: https://github.com/Rosuav/shed/blob/master/translit.pike The code's a bit messy, largely because the human languages involved are complex, but broadly, here's the plan: Mode 1: Reversible transliteration. In any of several modes (Cyrillic (Russian, Ukrainian, and Serbian variants), Korean, Elder Futhark, and Greek), it converts the input ASCII text into a non-ASCII script, and back again. Normally I use that to key in text that I can't otherwise type, but I can also copy and paste the other script and check it. Some of them also support diacriticals, as per the other mode. Mode 2: Latin-only mode. Fairly simple: the 'diacriticals' function just transforms some backslash escapes into individual Unicode characters, usually the combining ones, and then performs an NFC normalization on the resulting string. So, for instance (using Python string literal format; in actual usage, these would be single backslashes): Input: "\\!Sue\\'ltalo!" Step 1: "\u00A1Sue\u0301ltalo!" Step 2:"\u00A1Sue\u0301ltalo!" Step 3: "\u00A1Su\u00E9ltalo!" Displayed text: ¡Suéltalo! In usage, it's pretty simple. You key in a letter, then you hit backslash and a (usually mnemonically-appropriate) symbol, and it combines in an appropriate diacritical mark. There are a few oddities in the transformation table (for instance, "i\." produces a dotless i, but "I\." produces a dotted I; and "\-" produces a combining macron, unless it follows a D or d, in which case it produces a crossed D), so if you want to adapt this for your own use, you may want to throw out some of the transformations. But if you only occasionally have need of these kinds of letters, it may be easiest to just keep this handy, key in what you want, and then clipboard it to whatever you want to work with.

The good news is that after many, many years of supporting tab completion, Python 3.4 finally enables it by default. The bad news is that its handling of the tab key is fundamentally broken. There are a couple of tasks on the bug tracker dealing with this. I'm not able to search for them right now, but you may be able to find them: there is a task to enable tab completion by default, which I expect is closed by now, and (if memory serves me correctly) a second, open, task to fix the tab-for-indentation issue. As an alternative, you could try my tab completion and history module: http://code.google.com/p/tabhistory/ I've been using it on Linux for about three or four years, and although I don't promise it is bug-free, it shouldn't blow up your computer :-) You can read an announcement here: http://code.activestate.com/lists/python-list/672898/ Feedback from Mac and Windows users is very, very welcome. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

It would help us help you a lot of you copy/paste your code from both mydef.py
and test.py so we can see exactly what you're doing.
Don't re-type what you entered, because people (Especially new programmers) are
prone to either making typos or leaving out certain things because they don't
think they're important. Copy/Paste the code from the two files and then
copy/paste the error you're getting.

Python doesn't do variable substitution. At least not the way I think of it.
What do you mean by "variable substitution"?
Instead of "feeling" what the problem is, let's do some old-fashioned
debugging. Start by reading through the code, and in your head (or on
paper) trace through the possible lines that may be reached. The
_getPackgeVersion function has only 11 lines, it isn't hard. Here is your
function again:
def _getPackgeVersion(xmlfile, p):
package = str(p)
if isinstance(fpmdict["application"]["package"], list):
for i in fpmdict["application"]["package"]:
if i["@name"] == p:
_pkgVersion = i["version"]
else:
_pkgversion = fpmdict["application"]["package"]["version"]
return _pkgVersion
I can immediately see four problems:
(1) One branch of the "if isinstance" fails to return. So if the function
takes that branch, it will finish the loop, then exit the if...else clause,
then hit the end of the function and return None.
(2) Sometimes that branch may fail to set the _pkgVersion variable at all,
if none of the "@name" keys equal p.
(3) The other branch fails to set the _pkgVersion variable. Python is
case-sensitive, so _pkgversion and _pkgVersion are different variables.
(4) Your package variable is never used.
I don't know how to fix problem #2 since I don't know what behaviour would
be useful to you. So I'll just leave that for you. I can fix problems #1 #3
and #4:
def _getPackgeVersion(xmlfile, p):
if isinstance(fpmdict["application"]["package"], list):
for i in fpmdict["application"]["package"]:
if i["@name"] == p:
_pkgVersion = i["version"]
else:
_pkgVersion = fpmdict["application"]["package"]["version"]
return _pkgVersion
Now we can see that if _getPackgeVersion still returns None, the only way it
can do so is if the "version" key is set to have None as a value.
Are you sure that there is a "version" key set?
I can see another problem, earlier in your code:
for i in doc.get("application").get("instance", None):
...
That does not do what you expect. If there is no "instance" key, the second
get will return None, which is not iterable:
py> for i in None:
... pass
...

Preferred:

Almost.
Try this:
mydef.Fatalln()
Unless you import the symbols from your mydef module into your program
they have to referenced by the module name. This is a good thing and it
helps keep your code separated and clean. It is possible to import
individual symbols from a module like this:
from mydef import Fatalln
Avoid the temptation to import *all* symbols from a module into the
current program's namespace. Better to type out the extra bit.
Alternatively you can alias imports like this
import somemodule.submodule as foo
Frequently this idiom is used when working with numpy to save a bit of
time, while preserving the separate namespaces.

If you only do `import mydef`, then it creates a module object called `mydef`
which contains all the global members in mydef.py. When you want to call a
function from that module, you need to specify that you're calling a function
from that module by putting the module name followed by a period, then the
function. For example:
mydef.Fatalln("my test")
If you wanted to be able to call Fatalln without using the module name, you
could import just the Fatalln function:
from mydef import Fatalln
Fatalln("my test")
If you had a lot of functions in mydef.py and wanted to be able to access them
all without that pesky module name, you could also do:
from mydef import *
However, this can often be considered a bad practice as you're polluting your
global name space, though can be acceptable in specific scenarios.

I'm going to guess that writing the profile results is in a try/finally -- so
first you see the results being written,
then the exception that triggered.

Again, not what you asked for, but since you use Emacs . . . Are you
aware of Emacs's control-backslash ("toggle-input-method") command?
If I'm going to be writing French or Spanish, I hit control-backslash
and type "latin-prefix". Then, until I hit control-backslash again,
"'e" becomes é, "~n" becomes ñ, '"o' becomes ö, and many other
not-too-hard-to-remember things. Many other "input methods" are
available for other languages.
It's actually reminiscent of how Spanish typewriters used to work,
with an accent key that didn't advance the carriage.

Also, please be warned. If you use a unix system, or a linux
system. There are lots of problems you can get into if you
expect something named 'test' to run your code. Because they
already have one in their shell, and that one wins, and so ...
well, test.py is safe. But if you rename it as a script and call
it the binary file test ...
Bad and unexpected things happen.
Name it 'testme' or something like that. Never have that problem again.

Been there, done that!

I believe you are suggesting the apparent out-of-order is due to try/finally,
but kernprof is supposed to inject 'profile' into the global namespace, so
@profile should be defined - I don't know why it isn't working.

Ewww What a Ruby-esque interface, that makes me sad :-( And what if you have your own profile global name? And *wrong* too. `__builtins__` is a private CPython implementation detail. The way to monkey-patch the built-ins in Python 2 is to inject the object into `__builtin__` (no s), or `builtins` in Python 3. Seeing as line_profiler is written in C, perhaps the author (Robert Kern) doesn't care about supporting Jython or IronPython, but there may be Python implementations (PyPy perhaps?) which can run C code but don't have __builtins__. In any case, it sounds like it isn't working. Try creating this simple file: # demo.py print(profile) # Does profile actually get injected into the builtins? then running it: kernprof -l demo.py If that still gives a NameError, you have a bug in kernprof. Or possibly you have broken it -- perhaps you are accidentally shadowing one of its modules with a module of your own? -- Steven -- https://mail.python.org/mailman/listinfo/python-list

On OS X, the system provides both a "Character Viewer" (which allows the selection of any Unicode character and a "Keyboard Viewer" (which allows you to see the keyboard key mappings as keys and modifiers are pressed). Both can be enabled from System Preferences (System Preferences -> Keyboard -> Keyboard on current 10.10 systems). As of OS X 10.7 (I believe), there are also now popup menus that appear when various keys are held down that show accented variants of the character (this is similar to what iOS on the iPhone and iPad provide). Unfortunately, this doesn't work with some applicatons that do not use the full built-in text system; the Tk implementations on OS X are such applications so the popups don't work with Tkinter apps like IDLE.

Hi Python Users,
I currently installed the Python 2.7.9 and installed the GDAL package.
First, I tried to install GDAL using PIP but it throws an error - I cannot
remember the exact error message. So, I install it using easy_install
command. But when I import the package I am getting this message, which I
really don't understand.

From it's documentation: Interactively, prompt for CHARACTER. You can specify CHARACTER in one of these ways: - As its Unicode character name, e.g. "LATIN SMALL LETTER A". Completion is available; if you type a substring of the name preceded by an asterisk `*', Emacs shows all names which include that substring, not necessarily at the beginning of the name. - As a hexadecimal code point, e.g. 263A. Note that code points in Emacs are equivalent to Unicode up to 10 (which is the limit of the Unicode code space). - As a code point with a radix specified with #, e.g. #o21430 (octal), #x2318 (hex), or #10r8984 (decimal). For your "degree symbol" example, I did C-x 8 RET, then typed in *degree, and emacs found some matches, resulting in this: ° -- regards, kushal -- https://mail.python.org/mailman/listinfo/python-list

For slightly more frequent use (emacs-users) 1. Find a symbol such as ° maybe using google and paste it into emacs Does it exist in tex input method? To find out 2. Turn on tex input method (in some buffer) ie C-x RET C-\ and give tex (or whatever 3. C-u C-x = will tell info about the char. In particular it says: To input type \degree in tex input method I guess for diacritical marks one could use one of the latin-n input methods The above applied to á and latin-2-postfix says that á can be input with a' M-x describe-input-method will tell you others like +-+-- acute |'| a' -> á ogonek |,| a, -> ą diaeresis |"| a" -> ä circumflex |^| a^ -> â breve |~| a~ -> ă cedilla|,| c, -> ç caron |~| c~ -> č dbl. acute |:| o: -> ő ring |.| u. -> ů dot|.| z. -> ż stroke |/| d/ -> đ others |/| s/ -> ß -- https://mail.python.org/mailman/listinfo/python-list
Re: Wildly OT: pop-up virtual keyboard for Mac or Linux?
Kushal Kumaran : > For very, very occasional use in emacs, there's C-x 8 RET (insert-char). Emacs to the rescue, as usual. I use emacs for all of my typing needs. If I stray on a Web form, I end up cussing at the browser whenever I instinctively hit a C-n, C-a or C-s (or, yesterday, C-w). As for typing "special" characters, I have written a .Xmodmap file that rebinds my keyboard for various languages I use regularly. Then, I have this text file that contains specimens for many other useful characters. Marko -- https://mail.python.org/mailman/listinfo/python-list
