如何让这个随机列表只打印偶数

Question

I'm trying to make a program but it keeps doing something wrong. The program I'm trying to make is two functions. One that makes a random list(it returns it not prints it). The second function has to make that random list generate only even integers or numbers. (I'm in python 2 but python 3 might help too) Here's my code:

def random_list():
 res = random.sample(range(0, 50), 6)
 print str(res)
 
random_list()
 
def even_numbers():
   if (2 / 2 == 0):
       print(2)
 
even_numbers()

#What am I doing wrong?

Answer 1

You need to return the list of numbers from random_list :

import random


def random_list():
    res = random.sample(range(0, 50), 6)
    return res


def even_numbers(nums):
    for num in nums:
        if (num % 2 == 0):
            print(num)


my_numbers = random_list()
even_numbers(my_numbers)

Out:

48
36
22
