Not getting the return value

[menator01]

Another way:

#! /usr/bin/env python3
from random import randint

num1 = randint(20, 100)
num2 = randint(20, 100)
num3 = randint(20, 100)

def middle(nums):
    for num in nums:
        if num != min(nums) and num != max(nums):
            return num
print(f'Three numbers: {num1}, {num2}, {num3}')
print(f'Middle number is: {middle([num1, num2, num3])}')

Output:
Three numbers: 62, 37, 84
Middle number is: 62

And still one more

#! /usr/bin/env python3
from random import randint

nums = []
[nums.append(f'{randint(20, 100)}') for i in range(3)]
def middle(nums):
    return [num for num in nums if num != min(nums) and num != max(nums)]

print(f'Three numbers: {", ".join(nums)}')
print(f'The middle number is: {"".join(middle(nums))}')

Output:
Three numbers: 88, 57, 49
The middle number is: 57
