Converting a strng to an anonymous function

[Nathan Seese]

I'm writing a program to sort files with arbitrary python code. The
method I'm using for that is to pass sort an anonymous function taken
from the arguments. I'm wondering how to change a raw string into an
anonyous function.

Is this enough for you?

>>L = [1, -5, 7, -9]
>>sorted(L, key=abs)

[1, -5, 7, -9]

>>func = "abs"
>>sorted(L, key=eval(func))

[1, -5, 7, -9]

>>func = "abs(x)"
>>sorted(L, key=lambda x: eval(func))

[1, -5, 7, -9]
