I believe that Google has locked you out of your account.

Are you aware that you've just made your username and password visible to 
the entire Internet? If you hadn't already triggered Google's anti-spam 
detection, you surely have now.

When I log into your gmail account with those credentials, I see:



Verify your account

We've detected unusual activity on your account. To immediately
restore access to your account, choose how to verify your account.



so I believe Google have locked the account because they think you're 
spamming. You'll need to fix that before anything else.

Right, the only API change between 0.6 and 0.9 is the removal of the

because it hadn't worked in a long long time.



   Both Fedora and CentOS has python>=2.6, python3 is available for Fedora

xlrd 0.9 and above works with both python2 and python3 as-is.


   So can I release an update for all my Linux distributions with backward

I would suggest just going for 0.9.2.

There aren't any, because there are no changes. Applications written for

How do I encode and decode this data to write to a file?

[cl]

I am debugging some code that creates a static HTML gallery from a
directory hierarchy full of images. It's this package:-
https://pypi.python.org/pypi/Gallery2.py/2.0


It's basically working and does pretty much what I want so I'm happy to
put some effort into it and fix things.

The problem I'm currently chasing is that it can't cope with directory
names that have accented characters in them, it fails when it tries to
write the HTML that creates the page with the thumbnails on.

The code that's failing is:-

raw = os.path.join(directory, self.getNameNoExtension()) + ".html"
file = open(raw, "w")
file.write("".join(html).encode('utf-8'))
file.close()

The variable html is a list containing the lines of HTML to write to the
file.  It fails when it contains accented characters (an é in this
case).  Here's the traceback:-

Traceback (most recent call last):

If I understand correctly the encode() is saying that it can't
understand the data in the html because there's a character 0xc3 in it.
I *think* this means that the é is encoded in UTF-8 already in the
incoming data stream (should be as my system is wholly UTF-8 as far as I
know and I created the directory name).

So how do I change the code so I don't get the error?  Do I just
decode() the data first and then encode() it?

You can verify that your filesystem is set to use UTF-8 with 
sys.getfilesystemencoding(). If it returns 'ascii', then your locale settings
are incorrect.

Drag and drop in Windows

[Robert Flintham]

Hello all,

Sorry to post such a generic question, but after searching the interwebs I'm 
not really any wiser about how to start with this.

I'm currently on:
Windows XP
Python 2.7

I'm trying to create a small window in Python 2.7, that when you drop a file 
onto it from Windows explorer returns the file's path so that I can then go on 
to open the file and do whatever with it.  I was planning on using Tkinter 
because that's what I've used before for GUI's, but I can be swayed from this 
if needs be.

I've found this (TkDND):
http://wiki.tcl.tk/2768

But I don't know how to implement this in Python.  The Windows binary for it 
comes as a set of ".tcl" files and a single ".dll" file.

The two options I've stumbled across seem to be

1.  a Python wrapper for the DLL (I think to wrap C code??), which can then be 
imported like you'd import a Python package

2.  direct implementation of the Tcl file [tk.eval('source ...')], but I don't 
reallu understand what's going on with this - can you only execute a "main" bit 
of Tcl files rather than implementing individual functions?

Any input (however minimal) is definitely appreciated!  I've included what I 
think are probably the relevant functions from the Tcl files at the bottom of 
the email, but I don't really understand the nuts and bolts of the code.

All the best,
Rob

Note that you are getting a *UnicodeDecodeError*, not a UnicodeEncodeError. 
Try omitting the encode() step, i. e. instead of

> file.write("".join(html).encode('utf-8'))

use

file.write(""join(html))

Background (applies to Python 2 only): the str type deals with bytes, not 
code points. The right thing to do is to use .decode(...) to convert from 
str to unicode and .encode(...) to convert from unicode to str. In Python 2 
however the str type has an encode(...) method which is basically equivalent 
to

class str:
   # imaginary python implementation of python2's str
   ...
   def encode(self, encoding):
   return self.decode("ascii").encode(encoding)

and is almost never called intentionally.

PS Python3 has relabeled unicode to str and thus uses unicode by default. 
str was renamed to bytes and the annoying bytes.encode() method is gone.

What about simply testing whether the value returned by find is None? For 
example:

  $ cat test.py
  from xml.etree import ElementTree

  myTree = ElementTree.fromstring('')
  myElement = myTree.find('orange')

  if myElement is None:
  print 'tree does not contain a child element "orange"'
  else:
  print myElement.text


  $ python test.py
  tree does not contain a child element "orange"

HTH,

Please mention your Python version & OS.  Apparently you're running 2.7

I am debugging some code that creates a static HTML gallery from a
directory hierarchy full of images. It's this package:-
 https://pypi.python.org/pypi/Gallery2.py/2.0


It's basically working and does pretty much what I want so I'm happy to

You can't encode byte data, it's already encoded. So you're forcing the 
Python system to implicitly decode it (using ASCII codec) before letting 
you encode it to utf-8.  If you think it's already in utf-8, then omit 
the encode() call there.


Additionally, you can debug things with some simple print statements, at 
least if you decompose your 3-function line so you can get at the 
intermediate data.  Split the line into three parts;

temp1 = "".join(html) #temp1 is byte data
temp2 = temp1.decode()#temp2 is unicode data
temp3 = temp2.encode("utf-8")  #temp3 is byte data again
file.write(temp3)

Now, you'll presumably get the error on the second line, so examine the 
bytes around byte 783.  Make sure it's really in utf-8, and if it is, 
then skip the decode and the encode.  If it's not, then Andrew's advice 
is pertinent.


I would also look at the variable html.  It's a list, but what are the 
types of the elements in it?



 file.close()

The variable html is a list containing the lines of HTML to write to the

find returns None when it doesn't find what you asked for. So you
can't check the .text attribute right away unless you want an
exception thrown. I deal with these annoyances like this:

sepelem = content.find(".//{http://www.huawei.com.cn/schema/common/v2_1}sepid";)
if sepelem is not None:
   sepid = sepid.text
else:
   sepid = ''

The empty string works for my purposes. Your script might need
something else.

I haven't looked at the rest of the code, but be careful of this: You
aren't actually *calling* this function. That might be your problem

According to wikipedia 

"""
The size of each row is rounded up to a multiple of 4 bytes [...]
"""

So 48/8 == 6 will be rounded to 8, and 8*48 == 384 == 0x180.

To actually do something the last line should be handle1.close(). I 
recommend

with open(bmpfilename ,"rb") as handle1:
raw = bytearray(handle1.read())

instead which has the additional advantage that the file will be closed if 
an exception occurs in the with-suite.

[snip]
What size is 0x180?

If you're asking why the file size is 0x180 and not 0x120, it's simply
because of the header. An image file contains not just the pixels of
the image, but also information about the image.

The start of each line of bytes must be in the 32 bit=4byte 
boundary in the MS BMP format.

Mystery of module bindings!

This must be a trivial question:

I have "import numpy as np" in the python startup file.

A file called mod1.py contains "def myfn..."
 and inside myfn there is a call to, say, "np.convolve".

Interactively:

Error: global name "np" is not known.

Why is "np" not known to functions in an imported module ?

That only runs interactively. It does not run when you execute a script.

Let's suppose it was. What would that mean?

Look inside mod1, where there might be a function spam(), and also 
another function eggs(). spam() calls eggs(), it sees the eggs function 
in the same module, and all is well with the world.

Then you add to the startup file:

def eggs():
return "Something unexpected"


and all of a sudden mod1.spam() breaks, because it now sees *your* eggs() 
instead of its eggs. This would be a bad, bad thing.

This is why modules are their own namespace, and the interactive 
interpreter is its own, independent, namespace. What happens in the 
interactive interpreter stays in the interactive interpreter, without 
stomping all over every other module.

The point of the startup file is to add things to the interactive 
interpreter's module, not to inject things into every module in sight.

The startup file is only for interactive use.  Python programs in files 
shouldn't depend on a startup file, as it will limit their portability.  
In an interactive session, it's helpful to save some typing, but you can 
use explicit imports in programs, as they only need to be typed once, 
and will be used many more times.

Yes, you need a separate import from any module that references numpy. 
Don't worry about performance, subsequent imports do not take noticeable 
time, since the module objects are cached.


Any time you want to use a symbol from another module, you have to get 
it somehow. into your own module.  You do not have to get it from the 
import statement, but it's certainly the simplest way, and the way 
that's usually clearest.


Each module represents a namespace, and except for the global namespace 
which is handled specially, you have to describe which ones you want 
access to.  It's a feature, not a limitation.


There are lots of modules automatically imported indirectly by the ones 
you use.  A quick test on a local copy of Python 3.3 shows 51 modules 
imported before I write any code.  I certainly wouldn't want all of them 
visible in my script's namespace.


> -- but then what is the point of having a startup file?
>

Presumably by startup file, you mean script.  Without a script, Python 
wouldn't have any idea what code to run.  You import a few modules, use 
functionality from them, and lots of things happen behind the scenes. 
Fortunately for all of us, Python doesn't throw all the symbols into one 
big pile.

I can only comment on the Tcl side, since I'm not an expert in the 
Tkinter coupling mechanism. TkDND is indeed the way to go if you want 
native drag'n'drop support. The first step would indeed be to load the 
package into the Tcl interpreter. You need to:


1) Create a folder for the packages, put the files in a subfolder
Typically, this is something like lib/tkdnd, and at that level there 
must be the "pkgIndex.tcl" file

2) Append the lib/ folder to the auto path
tk.eval('lappend auto_path {mypath/lib}')
(the braces are Tcl's quoting mechanism)
3) load the package
tk.eval('package require tkdnd')

Then, you need to "register the target", i.e. declare a widget that it 
accepts files. Here, you need the Tk path name of the widget, which is 
retrieved by __str__:


tk.eval('tkdnd::drop_target register ' + yourwidget +' *')

Then, if you drop something, the widget recieves a virtual event 
<> . Now this is tricky, I don't know how to bind to 
that event. Following the tutorial for Tcl on http://wiki.tcl.tk/36708, 
I suppose something like


yourwidget.bind("<>", filesdropped)

should in principle work, but how to get the data out of it? It is 
stuffed into the %D bind substitution. Usual events store the MouseWheel 
distance in this field; so maybe you can get it from the field 
event.delta. I can't test it now, but I am a bit skeptical whether this 
works with the guts of TkInter. If not, you'd need to do some more 
forwarding from the Tcl side.

That "fix" is indeed the way things are done.  Modules only know about what 
they import or create*.

The point of the startup file is to have things ready for interactive investigation -- if you use numpy *alot* then 
having it already there beats the heck out of typing `import numpy as np` every time you start the interpreter.

I don't know what you mean by your "clause", and I think we have a
language barrier here. (Though your English is *way* better than my
French.) But for a simple rule of thumb, the only things you should
have flush left are "def" and "class" statements, and the one "if"
that checks __name__. Everything else should be indented.

This also makes it possible to print intermediate results.
  print(type(s), s)  # would have been useful
Doing so would have immediately shown that in this case the error was 
the encode operation, because s was already bytes.
For many other posts, the error with the same type of message has been 
the print or write operation, do to output encoding issues, but that was 
not the case here.

repeat program

[eschneider92]

How do I make the following program repeat twice instead of asking whether the 
player wants to play again?


import random
import time

def intro():
print('You spot 2 caves in the distance.')
print ('You near 2 cave entrances..')
time.sleep(1)
print('You proceed even nearer...')
time.sleep(1)

def choosecave():
cave=''
while cave!='1' and cave !='2':
print('which cave?(1 or 2)')
cave=input()
return cave

def checkcave(chosencave):
friendlycave=random.randint(1,2)
if chosencave==str(friendlycave):
print ('you win')
else:
print('you lose')

playagain='yes'
while playagain=='yes':
intro()
cavenumber=choosecave()
checkcave(cavenumber)
print('wanna play again?(yes no)')
playagain=input()

Thanks in advance.

Turn it into a function call, and call that function twice from 
top-level.  Or, more generally,




for i in range(2):
doit()




import random
import time

def intro():
 print('You spot 2 caves in the distance.')
 print ('You near 2 cave entrances..')
 time.sleep(1)
 print('You proceed even nearer...')
 time.sleep(1)

def choosecave():
 cave=''
 while cave!='1' and cave !='2':
 print('which cave?(1 or 2)')
 cave=input()
 return cave

def checkcave(chosencave):
 friendlycave=random.randint(1,2)
 if chosencave==str(friendlycave):
 print ('you win')
 else:
 print('you lose')

playagain='yes'
while playagain=='yes':
 intro()
 cavenumber=choosecave()
 checkcave(cavenumber)
 print('wanna play again?(yes no)')
 playagain=input()

Thanks in advance.

Replace the 'while' loop with a 'for' loop that loops twice.

By the way, there's a bug in 'choosecave': what happens if the user
enters, say, '3'?

You change something in the folowing two lines:

playagain='yes'
while playagain=='yes':

What you change and how you change it is probably your homework task, so 
I really shouldn't tell you any more than that.

Also, I might not be right about where you need to make the change, but 
hey, this is the internet, it must be right, yeah?

Re: Unwanted window spawns when using Tkinter with multiprocessing.

[alternative00]

I thought 'clause' was reffering to the 'if __name__ == "__main__":' thing in 
English, but apparently not. 
Well except the import and the 'globalization' of my variables, every thing is 
idented.

No clue whom you think you're replying to, but all your replies so far 
are appearing in the thread as replies to your OP.  Please use a little 
context from the message you think you're responding to, so we have an 
idea what you're talking about.


Did you ever see MRAB's message, where he told you exactly what the 
change requested was?



if __name__ == "__main__":
# This part will be run if the file is run as the main script.
#
# The multiprocessing module will import this file to run the
# "player" function, but __name__ won't be "__main__" when it does
# so, therefore this bit of code won't be run.

#Initialisation
fenetre = Tk()
frame = Frame(fenetre, width=200, height=100)
instance = 'Instance'

#TK
frame.focus_set()
frame.bind("", key)
frame.pack()
fenetre.mainloop()

All of those lines were at the left margin in your earlier posted code, 
and you give us no reason to expect you've made them conditional.
