I’ve been trying to create and change a function dynamically in Python. I’ve researched the web and Stack Overflow, but most solutions I see use one of the following, which I don’t want:

1. exec() and/or compile()
2. lambdas
3. closures and nested functions

For example, I have the following code:

def func(a, b, c):
    return all([a, b, c])

and I want to change it to:

def func2(a, b, c):
    return any([a, b, c])

However, for some reasons I am not allowed to change the code of the function. Is there any way I can do this? I’m looking for a code bytes alternation kind of thing or AST related solution. Any ideas?
