Question

I’m probably not using the right terminology, but I’m learning python and I’m trying something that I can easily do in Lua:

def fire(self):        
    return self._loadModule()[self._entrypoint]() #subscripting the module raises an error

def _loadModule(self):
    return __import__(self._module)

I want to load the module and then call an arbitrary function inside that module. What is correct way to do this?

EDIT:
Module and entry point names are determined at runtime.

Answer 1

If I understand it right; a completely useless example:

def my_sqrt(num):
    import math #load a module
    return math.sqrt(num) #call the function

From string:

>>> def f(module, function, *args):
...     return(getattr(__import__(module), function)(*args))
... 
>>> f("math", "sqrt", 2)
