python - 为什么我得到 : invalid syntax error on python3

Question

我正在用 python3 制作拾取棒游戏。 共有 20 根棍子，每位玩家一次最多可以捡起 3 根棍子。 当我运行这段代码时，我一直在第 8 行收到无效语法错误，它指向 0。

我错过了什么吗？我认为我的缩进很好，不是吗？

stick_left = 20
for _ in range(5): print('|  '*stick_left) 
player1 = 0
player2 = 0
game_over = 0
while (game_over!=1):
    first_pick = input("Player1: pick any sticks up to 3 ")
    if first_pick > 3 or first_pick < 0
        print('Please pick between 1-3 sticks')
    else player1+=first_pick
    second_pick = input("Player2: pick any sticks up to 3")
    if second_pick > 3 or second_pick < 0
        print('Please pick between 1-3 sticks')
    else player2+=second_pick
    stick_left -= first_pick + second_pick
    for _ in range(5): print('|  '*stick_left)

在我继续工作之前，我只想确保第一部分工作正常，然后我可以继续下一部分。 提前致谢!

if、else 语句中缺少冒号(:):

while (game_over!=1):
    first_pick = input("Player1: pick any sticks up to 3 ")
    if first_pick > 3 or first_pick < 0:  # <---
        print('Please pick between 1-3 sticks')
    else: player1+=first_pick  # <---
    second_pick = input("Player2: pick any sticks up to 3")
    if second_pick > 3 or second_pick < 0:  # <---
        print('Please pick between 1-3 sticks')
    else: player2+=second_pick  # <--
    stick_left -= first_pick + second_pick
    for _ in range(5): print('|  '*stick_left)
