我不理解此语法错误 是python 3的新功能

不确定这里是否有错误，在第19行出现语法错误。删除冒号会使错误向前移动。我认为这可能与缩进有关，但我不确定。

import time 
import random

print('Scissors? Paper? or Rock?')
playerchoice = input()

if playerchoice == 'rock' | 'Rock' | 'ROCK' | 'r' | 'R':
    playerval = 1 
elif playerchoice == 'scissors' | 'Scissiors' | 'SCISSORS' | 's' | 'S':
    playerval = 2
elif playerchoice == 'paper' | 'Paper' | 'PAPER' | 'p' | 'P':
    playerval = 3
else: 
    print('Invalid input')

roboval = (random.randint(0,4)


if roboval == 3 & playerval == 1:
    playerval = 4

if playerval == 3 & roboval == 1: 
    roboval = 4

if playerval > roboval:
    resultwin = 1
else: 
        resultwin = 0
