I don't see how to make it simpler in Python. This looks less clear
than a direct 'for' loop IMHO:

def call_method_for(objects, method, *args):
    for o in objects:
        getattr(o, method)(*args)

call_method_for(objects, 'method', args)

There is little to abstract away because there is no good way to express
"a method to call". Another approach is to express it with a function:

def call_for(objects, f):
    for o in objects:
        f(o)

call_for(objects, lambda o: o.method(args))

Not an improvement either.
