Creating a Rock Papers Scissors Program and there seems to be an error in My Code

I'm just beginning to learn python. I'm creating a little rock paper scissors game.

Line 8 seems to be my problem ("def rock_logic():"). The VS studio code debugger says "invalid syntax (, line 8)pylint(syntax-error)"

I've looked through both Automate the boring things and Colts Steele's "The Modern Python 3 Bootcamp," but I can't seem to find the solution.

import random
choices = ['rock', 'paper', 'scissors']
user_choice = input()
comp_choice = random.choices()
print("ROCK! PAPER! SCISSORS!")

def rock_logic():
    if user_choice = 'rock' and comp_choice = 'rock':
        print ('TIE')
    elif user_choice = 'rock' and comp_choice = 'paper':
        print('YOU LOSE')
    else:
        print('WINNER WINNER CHICKEN DINNER')

def paper_logic():
    if user_choice = 'paper' and comp_choice = 'paper':
        print ('TIE')
    elif user_choice = 'paper' and comp_choice = 'scissors':
        print('YOU LOSE')
    else:
        print('WINNER WINNER CHICKEN DINNER')

def scissors_logic():
    if user_choice = 'scissors' and comp_choice = 'scissors':
        print ('TIE')
    elif user_choice = 'scissors' and comp_choice = 'rock':
        print('YOU LOSE')
    else:
        print('WINNER WINNER CHICKEN DINNER')
