Question

I want to basically turn a list element into a function with the do function. This way any pre-written funcction i can call by just use a do(list[x]).

Answer 1

If you really want to execute arbitrarily named functions from a list of names in the current global/module scope then this will do:

NB: This does NOT use the potentially unsafe and dangerous eval():

Example:

def func():
    return "python"


def func1():
    return "is"


def func2():
    return "awesome"


def do(func_name, *args, **kwargs):
    f = globals().get(func_name, lambda : None)
    if callable(f):
        return f(*args, **kwargs)


funs = ["func", "func1", "func2"]

print "".join(funs[0])
print "".join(map(do, funs))

Output:

$ python foo.py
func
pythonisawesome

You can also individually call "named" functions:

>>> do(funs[0])
python

Note the implementation of do(). This could also be applied more generically on objects and other modules too swapping out globals() lookups.
