Python - How to pass a method as an argument to call a method from another library

Question

I want to pass a method as an argument that will call such method from another python file as follows:

file2.py

def abc():
    return 'success.'

main.py

import file2
def call_method(method_name):
    #Here the method_name passed will be a method to be called from file2.py
    return file2.method_name()

print(call_method(abc))

What I expect is to return success.

If calling a method within the same file (main.py), I notice it is workable. However, for case like above where it involves passing an argument to be called from another file, how can I do that?

Answer 1

You can use getattr to get the function from the module using a string like:

import file2
def call_method(method_name):
    return getattr(file2, method_name)()

print(call_method('abc'))
