Good for you. (Sorry, that comes across as more condescending than it is
intended as.) Monkey-patching often gets used for quick scripts and tiny

Just beware that if you extend that technique to larger bodies of code,

In simple terms, when you create an immutable object it can contain

As long as you don't use any features of the Cython language, it's plain

Tell that the C++ guys. C++ is mainly a superset of C. But nevertheless,
C and C++ are distinct languages and so are Python a

Or at least keys or key combinations for the stuff you need, which might

I'm totally confused by this code:
Code:
a = None

c = None
d = None
x = [[a,b],
[c,d]]
e,f = x[1]
print e,f
c = 1
d = 2
print e,f
e = 1
f = 2

This breaks a lot of my code because in python 2

Of course. I only wanted to point out that os.system() is an even worse
