a problem with importing pygame
I use python for my school work and I wanted to download it at home. I had my teacher download the version to a flash drive and it still doesn't seem to work. The version that I got from the flash drive was python 3.4.2 and I think I got a 32 bit or a 64 bit pygame for a windows machine. The program does not import pygame, it says that there is no module named pygame. -- https://mail.python.org/mailman/listinfo/python-list

Jussi forgot to add the "..." line to the group. To fix this change the
generator to
def records(source):
current = []
for line in source:
current.append(line)
if line.startswith(''):
yield current
current = []
>> hasmango(record) or print(*record)
The
print(*record)
inserts spaces between record entries (i. e. at the beginning of all lines
except the first) and adds a trailing newline. You can avoid this by
specifying the delimiters explicitly:
if not hasmango(record):
print(*record, sep="", end="")
Even with these changes code still looks somewhat brittle...

That's a nuisance. I wish otherwise undefined escape sequences in
strings raised an error, similar to a stray space after a line
continuation character.

I didn't forget. I meant what I said when I said the OP needs to adapt
the code to (among other things) restore the end marker in the output.
If they can't be bothered to do anything at all, it's their problem.
It was already known that this is not the actual format of the data.

Oops, I notice that I forgot to start a new record only on encountering
a '' line. That should probably be done, unless the format is
intended to be exactly a sequence of "\n- -\n\n".

Yes, I forgot about the space. Sorry about that.
The final newline was intentional. Perhaps I should have added the end
marker there instead (given my preference to not drag it together with
the data lines), like so:
print(*record, sep = "", end = "\n")
Or so:
print(*record, sep = "")
print("")
Or so:
for line in record:
print(line.rstrip("\n")
else:
print("")
Or:
for line in record:
print(line.rstrip("\n")
else:
if record and not record[-1].strip() == "":
print("")
But all this is beside the point that to deal with the stated problem
one might want to obtain access to a whole record *first*, then check if
it contains "mango" in the intended way (details missing but at least
"mango\n" as a full line counts as an occurrence), and only *then* print
the whole record (if it doesn't contain "mango").
I can think of two other ways - one if the data can be accessed only
once - but they seem more complicated to me. Hm, well, if it's XML, as
stated in another branch of this thread and contrary to the form of the
example data in this branch, there's a third way that may be good, but
here I'm responding to a line-oriented format.

That depends on the actual data format, and on what really is intended
to trigger the filter. This approach is a complete waste of effort if
there are no guarantees of things being there on their own lines, for
example.
Ok, that "\ " not only looks brittle but actually is brittle. The one
time I used that slash,

Can't run lpr from python on windows 2012 server
I am reposting this question in a simpler form.
I can run lpr from the command prompt but not from python
os.system("notepad") works
os.system("lpr") does not work. Basically it says lpr is not a known program or
executable
Why can I run lpr from the windows command prompt but not from python(2.7)

Does lpr.exe actually physically exist in c:\windows\system32 as you
have indicated in the your earlier posts? I.e. if you actually browse
system32 with the file manager will you see lpr.exe? The problem with
your question is that it's not a standard command, so none of the rest
of us have it, which means we're half-blind trying to find your problem.

Remove directory tree without following symlinks
I want to remove a directory, including all files and subdirectories under
it, but without following symlinks. I want the symlinks to be deleted, not
the files pointed to by those symlinks.
E.g. if I have this tree:
parent/
+-- spam/
: +-- a.txt
: +-- b.txt
: +-- eggs/
: : +-- c.txt
: : +-- surprise -> ../../parent
: +-- d.txt
+-- e.txt
and I call remove_tree("parent/spam"), I want the result to be:
parent/
+-- e.txt
(Assuming that I have permission to delete all the files and directories.)
What should I use for "remove_tree"? Do I have to write my own, or does a
solution already exist?

I am not convinced that it is a cycle in the technical sense, or that the two algorithms that Oscar linked to will necessarily find them. They may, by chance, happen to find them sometimes, but the way the algorithms work is by detecting periodic behaviour, and this is not periodic. Look at the comment for Floyd's algorithm here: https://en.wikipedia.org/wiki/Cycle_detection # The hare moves twice as quickly as the tortoise and # the distance between them increases by 1 at each step. # Eventually they will both be inside the cycle and then, ... but that is violated in this scenario. The hare can escape the (non-)cycle before the tortoise even enters it. Even if both enter the "cycle", there's no guarantee that the termination condition `tortoise == hare` will ever be true because the cycle doesn't loop and doesn't go back to the beginning. Hence it is not a cycle. > If the stack got overflowed, there won't usually be a part 3, as part > 2 is the bit that hits sys.recursionlimit (unless increasing the > recursion limit by a finite number would solve the problem). Don't just think of breaking the recursion limit. You might be 100 calls deep in some complex chain of function calls when something raises ValueError. In principle, there might not even be any recursive calls at all. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

It's under "Print and Document Services" -> "LPR Port Monitor". It only installs a 64-bit build, which is why loial is having trouble running it from 32-bit Python. But in Windows 7+ (Server 2008 R2), a 32-bit process can use the virtual "%SystemRoot%\SysNative" directory to access files in the native System32 directory.

The os.walk recipe is described as a simple version of shutil.rmtree. The documentation for rmtree seems lacking to me, but after testing it, it appears to work as I want it: it removes symbolic links, it does not follow them.

FYI, Just today I found out that shutil.rmtree raises a WindowsError if the dir is read-only (or its contents). Using 'ignore_errors', won't help. Sure, no error is raised, but the dir is not deleted either! A 'force' option would be a nice improvement. > The os.walk recipe is described as a simple version of shutil.rmtree.

Have you tried my dbf package? https://pypi.python.org/pypi/dbf I'm pretty sure it handles such values. -- ~Ethan~ -- https://mail.python.org/mailman/listinfo/python-list

Use the onerror handler to call os.chmod(path, stat.S_IWRITE). For example, see pip's rmtree_errorhandler: https://github.com/pypa/pip/blob/8.1.1/pip/utils/__init__.py#L105 -- https://mail.python.org/mailman/listinfo/python-list

Since you're not using those fields that won't be a problem (otherwise you would have filter them out). -- ~Ethan~ -- https://mail.python.org/mailman/listinfo/python-list

If they start with two underscores then you could use the name mangling to find them. If the class name is MyClass then look for any keys in the instance dict that start with '_MyClass__'. Otherwise no, you'd have to list them explicitly. -- https://mail.python.org/mailman/listinfo/python-list

Of course classes in Python are very useful. It's just that your Java habits are unnecessary and often counter-productive. Just make some globals and some functions. Heck, even write procedurally for a while.
