You should look into using PyQt or PySide. They are python bindings for
the very popular Qt GUI framework.

Define your colors as actual number variables instead of a string
color = (255,0,0)
color2 = (0,0,255)
Then use argument expansion to pass them in as separate arguments to the
function
colorFunction(*color)

For-loops are no different. Making them their own namespace is a very
strange thing to do, it would mean you couldn't re-bind a value inside a
for-loop:
count = 0

Yes, loops don't have their own scope. Indeed, very few flow elements in
python -- if, with, try/except -- create a new scope. In that sense, it's
fairly consistent, but can be unexpected for people that have used
languages with many nested scopes.
The lambda behavior is a common gotcha - there

It's usually the opposite. When packages are split up, you only have to
load the specific portions you need. Putting it all in a single module
forces you to always load everything.

Unless you're actually distributing python (as in, the interpreter or it's
source code), you don't need to include the python license or the copyright
notice. You also don't need a Contributor agreement just to distribute a
python library. That is more for people who are contributing to core

This looks like a decorator function that optionally accepts arguments to
change the behavior.
You can safely ignore the warning form PyCharm. the variable won't be

A lot of times, the outside decorator will just use the *ar
Generally, all your unittests will be inside a "tests" directory that lives
outside your package directory. That directory will be excluded when you
build or install your project using your setup.py script. Take a look at
some popular 3rd party python packages to see how they structure their

You could create your own generator that wraps enumerate

yield len(iterable) - 1 - i, val

A lot of these arguments and points have already been made and hashed out
on the python-dev list. There's a very good article that one of the python
core developers wrote about the decision to move to github
http://www.snarky.ca/the-history-behind-the-decision-to-move-python-to-github
Basically,
Consider the following example python package where `a.py` and `b.py`
depend on each other:
/package
__init__.py
a.py
b.py
There are several ways I could import the "a.py" module in "b.py"
import package.a # Absolute import
import package.a as a_mod
I have a relatively large python package that has several cyclical
dependencies. The cyclical dependencies typically aren't a problem so long as
I'm just importing modules, and not named attributes (ie. function, class,
globals), which may not be defined at a given point in the import routine

While I think most of the disagreement in this long thread results
from different beliefs in what "freedom" means, I wanted to add, that
most of the responses that argue that the MIT license permits the user
more freedom than the GPL, suffer from the broken window fallacy.
This fallacy results from

If you want to get the function name from within the function itself,
check out the inspect module.
