I recommend downloading and installing 7-Zip, which is free and handles more formats. It will let you extract the contents, which you can then install normally with the setup script as shown above.

It runs fine in pythonWin performing the same entry operation. Open a
menu, select an item to open a dialog, select a select button in the
dialog, press OK to leave the dialog. Boom, as above.
(This does not mean pythonWin doesn't have problems of its own. ) If I
just execute the code (double click on the py file, the console shows no
problems. IDLE is unhappy.
Another side to this is that I use WinMerge to find differences between
my last saved copy and the current copy. I found the current copy had
two lines where a abc.get() was changed to abc.get. This was undoubtedly
from briefly using the pyWin editor, when I mis-hit some keys. Yet pyWin
had no trouble executing the program. My guess is that while briefly
editing there, I hit some odd combination of keys that produced,
perhaps, an invisible character that pyWin ignores.
Not the 34672232 window is a dialog that I closed by pressing OK. I
would again guess, that, if there is a problem, it occurs in the code
that destroys the dialog.
Well you have to remember that you are trying to run a windowed GUI
under the control of another windows GUI, so it isn't surprising that
you hit trouble.
With IDLE the issue will be that IDLE already created a main window
before your program started running. With PythonWin you are using two
different toolkits, so it isn't really surprising that breaks down -
there will be two entirely separate main loops competing with each other.
Not quite. I take down IDLE when I run pyWin, and vice versa.
The two separate loops being PyWin (which uses MFC) and your program
(which uses Tkinter). You just can't mix GUIs in the same process like
that, sorry.

Re: Looking for the best way to translate an idiom
On Dec 14, 11:19 am, Paul Moore p.f.mo...@gmail.com wrote: I'm translating some code from another language (Lua) which has multiple function return values. So, In Lua, it's possible to define a function function f() return 1,2,3 end which returns 3 values. These can then be used/assigned by the caller: a,b,c = f() So far, much like Python, but the key difference is that in Lua, excess arguments are ignored - so you can do a = f() or even a = f() + 1 where in the latter, a is 2 (as addition only needs 1 argument, so the extra ones are discarded). This results in the code which I'm trying to translate having functions which return multiple arguments, the first of which is the main result, and the following values are extra results (specifically, the position at which a match is found, followed by the captured values of the match). I'm trying to find a natural equivalent in Python. So far, I've considered the following: - return a tuple (pos, captures). This is messy, because you end up far too often unpacking the tuple and throwing away the second value - return an object with pos and captures attributes. This is better, as you can do match(...).pos to get the position alone, but it doesn't really feel pythonic (all those calls with .pos at the end...) - have 2 calls, one to return just the position, one to return both. This feels awkward, because of the 2 method names to remember. To make things worse, Lua indexes strings from 1, so it can use a position of 0 to mean no match - so that a simple did it match? test looks like if (match())... - where in Python I need if (matchpos(...) != -1)... (Although if I return a match object, I can override __nonzero__ to allow me to use the simpler Lua form). Can anyone suggest a good idiom for this situation? At the moment, I'm returning a match object (the second option) which seems like the least bad of the choices (and it mirrors how the re module works, which is somewhat useful). But I'd like to know what others think. If you were using a pattern matching library, what interface would you prefer? I suspect my intuition isn't accurate here, as most of the use I've made of the library is in writing tests, which isn't typical use :-( Thanks for any assistance.
