Store functions in list and call them later

Question

I want to store functions in a list and then later in a program call those functions from that list.

This works for me, however, I don't know if it is correct :

#example functions, my functions would actually get user input etc.
def func1():
    return 2
def func2():
    return 3

options = [ func1, func2 ]

#call functions

options[0]()

Is this the proper way to store functions in a list and call it ? Or is there a different, better way to do this?

Answer 1

Yes, you can do it. If you want to call all functions in the list with a "one liner" you can do the following:

results = [f() for f in options]

Answer 2

Yes, this is correct, though if your functions are really one-liner in nature, I would suggest you also have a look at lambdas, so that your entire code can be reduced to:

options = [lambda: 3, lambda: 2]

As already pointed out in comments, you will Of course need to remember the order of the functions in the list.
