If and elif statements not working/not being recognised by python

I am trying to create a little Rock paper scissors game as I am a beginner but I am having issues with my if and elif statements.

'''

import random
player_score = 0
computer_score = 0
options = ['rock', 'paper', 'scissors']

def player_choice():
    input('Rock, Paper or Scissors? ')
    return player_choice
def computer_choice():
    print(random.choice(options))
    return computer_choice

ps = print('player score: ', player_score)
cs = print('computer_score: ',computer_score)

while player_score or computer_score < 10:
    player_choice()
    computer_choice()

if player_choice == 'rock' and computer_choice == 'rock':
        print('Tie')
elif player_choice == 'rock' and computer_choice == 'paper':
        print('Computer wins')
        computer_score = computer_score + 1
        print(ps)
        print(cs)
elif player_choice == 'rock' and computer_choice == 'scissors':
        print('You win')
        player_score = player_score + 1
        print(ps)
        print(cs)

It seems as though the entire if/ elif block is ignored and nothing prints or is incremented. No error pops up, it is just simply ignored.
