How to run functions in random order?

I want to run functions with random order. It looks like "shuffle" function which shuffle a variables list.

Input:

def a():
    print('a')

def b():
    print('b')

def c():
    print('c')

shuffle([a,b,c])

This is output what I want:

a
b
c

or

a
c
b

or 

c
b
a

or etc How to run functions with random order?

random.shuffle is an in-place operation. So you need to keep the list separately and shuffle it.

import random

functions = [a, b, c]
random.shuffle(functions)

Now, the functions are shuffled and you just have to execute them

for func in functions:
    func()

You can probably store this in a function and do it like this

def run_functions_in_random_order(*funcs):
    functions = list(funcs)
    random.shuffle(functions)
    for func in functions:
        func()

run_functions_in_random_order(a, b, c)

Or you can simply use the functions in closures, like this

def run_functions_in_random_order(*funcs):
    def run():
        functions = list(funcs)
        random.shuffle(functions)
        for func in functions:
            func()
    return run

random_exec = run_functions_in_random_order(a, b, c)

random_exec()
random_exec()
random_exec()

Here is how I would do. Basically what thefourtheye has suggested. Run this Code

from random import shuffle

def a():
    print('a')

def b():
    print('b')

def c():
    print('c')

def main():
    lis = [a,b,c]

    shuffle(lis)

    for i in lis:
        i()

Or make a list and take random: 

import random  

def a():
    print('a')

def b():
    print('b')

def c():
    print('c')  

my_list = [a, b, c] 
random.choice(my_list)()
