How can I force update the Python locals() dictionary of a different stack frame?
In Python 2 (not sure about 3), the locals dictionary only gets updated when you actually call locals(). So e.g.
l=locals()
x=2
l['x']
fails because l doesn't have the key "x" in it, but
l=locals()
x=2
locals()
l['x']
returns 2.
I'm looking for a…

Compilation implications of declaring all scope locals in the beginning as in early C?
I remember hearing that lining up all scope members in the beginning of the block was no longer recommended practice with both C and C++, but does this mean it obstructs the compiler in some way when generating code, or simply that it is no longer…

Example:

NB: This question assumes Python 2.7.3.
I'm looking for a sane approach to dynamically modify a function's local namespace, preferably in a way that adds the least clutter to the body function.

When you declare a variable of the same name both inside and outside the class/function, how do you know which value of the variable will be used?
a=0
b=1
class A:
a=42
b=list((a,a+1,a+2))
x=A()
print(x.b)
output: [42, 43, 44]
VS
a=0
b=1
class A:
a=42
b=list((a+i for i in range(3)))
x=A()
print(x.b)
output: [0, 1, 2]
So in the first example, a=42 was used. But in the second…
