Hi all,
I'm writing a small GUI on OS X (v. 10.7.4) using Tkinter. I'm using
stock Python. It mostly works fine but there is a bug in Entry
widgets: if and Entry widget has focus and I press the UP arrow, a
"\uf700" gets inserted in the widget. If I press the DOWN arrow, a
"\uf701" gets inserte

Hi all,
I'm looking for a way to run Lua scripts in Python, and also send and
receive data between the two. Something like lunatic-python [1] would
be ideal. However, so far I haven't been able to build it on the
machines it's supposed to run on (macs with OS X Lion) and it seems to
be dormant.

Interesting! I definitely fall nicely at one extreme of this
dichotomy. Every time I've tried to use an IDE, it's made me feel
inadequate and I've quickly retreated to my comfort

Hi all,
In Python 3, a function f's code object can be accessed via f.__code__.
I'm interested in getting a module's code object, i.e. the code that
is executed when the module is run. I don't think it's accessible via
the module object itself (although I would be glad if somebody proved
me wron

Hi all,
Here is an extract from the dis module doc [1]

Hi all,
I'm wondering what advice you have about formatting if statements with
long conditions (I always format my code to <80 colums)
Here's an example taken from something I'm writing at the moment and
how I've formatted it:
if (isinstance(left, PyCompare) and isinstance(right, PyComp

Hi all,
Unpyc3 can recreate Python3 source code from code objects, function
source code from function objects, and module source code from .pyc
files. The current version is able to decompile itself successfully
:). It has been tested with Python3.2 only.
It currently reconstructs most of Python

Hi all,
You can do:
def foo():
"foodoc"
pass
function = type(lambda:0)
foo2 = function(foo.__code__, globals())
assert foo2.__doc__ == "foodoc"
I am wondering how the function constructor knows that foo.__code__
has a docstring. I can see that
foo.__code__.co_consts == ('foodoc',)
