我已经检查并调试了你的代码。然后我发现了一个问题当你 color_code = ['R','G','G','G'] 及 player_guess ='GGGG' 当程序第一次尝试比较时 correct_color 具有 prev_curt_color . 它们都等于0。所以当你想计算出正确颜色和错误位置的数字时。它将显示0而不是1。下面是已编辑的代码。

if correct_color != 4:
    for i in range(4):
        if player_guess[i] == color_code[i]:
            correct_color += 1
            prev_curt_color = correct_color
        elif player_guess[i] != color_code[i] and player_guess[
                i] in color_code and correct_color >= prev_curt_color:
            guessed_color += 1

顺便说一句，看来你应该学习如何调试python程序这里是一个教程，希望它能帮助调试教程
