如何在python中随机function内的select函数

Question

I have two functions doing different operations but I would like them to be called in another function randomly.

eg.

def func1(): do something
def funct2(): do something else

def func3(): select funct1() or funct2() randomly

Answer 1

Collect the functions in a list and randomly choose one of them (using random.choice ) and call it!

>>> def f2():
        return 2

>>> def f1():
        return 1

>>> fns = [f1, f2]
>>> from random import choice
>>> choice(fns)()
1
>>> choice(fns)()
2

This is possible because Python functions are first class objects. Read up this link on first class objects in Python .

Answer 2

Another way of doing it...Instead of choosing function choose digits and assign functions to them

import random
def f1():
    print('Good Morning')
    return 'Hi'
def f2():
    print('Good Night')
    return 'Hello'
if random.randint(1,2)==1:
    print(f1())
else:
    print(f2())

The output:

Good Night
Hello
