Python不接受我的输入，我做错了什么？

Question

我正在为主脑游戏创建代码，我认为一切都应该是完美的，但是当我尝试编写第一个输入所需的信息时（在这种情况下，像“R”这样的颜色，这对我来说无关紧要这会直接跳到打印（“你必须引入四种颜色，不多也不少！”）

有人可以帮我吗???

这是代码：

colours=["R", "G", "B", "Y", "W", "R", "P"]
attempts=0
game=True


codemaker=random.sample(colours,4)
print (codemaker)

while game:
    white_points=0
    black_points=0
    guessed_colour=""
    player_guess=input().upper()
    attempts+=1

    if len(player_guess) != len(codemaker):
        print ("You have to introduce four colours, no more, no less! ")
        continue

用打印进行一些轻量级的调试，你会发现代码完全符合你的要求：它不打印（“你必须引入四种颜色，不多也不少！”）当长度是同样4：

import random

colours=["R", "G", "B", "Y", "W", "R", "P"]
attempts=0
game=True

codemaker=random.sample(colours,4)
print(len(codemaker), codemaker)

while game:
    white_points=0
    black_points=0
    guessed_colour=""
    player_guess=input().upper()
    attempts+=1
    print(player_guess, len(player_guess))

    if len(player_guess) != len(codemaker):
        print("You have to introduce four colours, no more, no less! ")
        continue
