Question

我是Python和Tkinter的新手。这是我用GUI练习的游戏。我遇到的问题是当重新启动新游戏时，代码允许输家给出第一个猜测。这是一个我无法解释的无意识的加号。我的代码旨在为玩家1提供第一次猜测，但这并不会发生。我已经完成了尽职调查，并认为问题出在reset_game方法和player_guess方法之间的转换中。请描述为什么我的代码在重新启动游戏时没有给予player1第一个猜测。如果对格式，结构，干燥问题等有任何意见，我也会很感激。

在player_guess中，获胜者在game_play中决定。

如果有胜利者，您正在使用reset_game重置游戏，但您的代码会在game_play返回后继续并更改条目状态。 game_play应该是player_guess应该做的最后一件事。

def player_guess():
    if p1_entry.get():
        ....
        game_play(guess)
    else:
        ....
        game_play(guess)

或者只是将game_play移出if-elses，因为无论如何都要调用它。

def player_guess():
    if p1_entry.get():
        ....
        guess = int(p1_entry.get())
    else:
        ....
        guess = int(p2_entry.get())

    game_play(guess)
