我正在构建一个Guess the Number游戏，并且希望能够实现它，所以你必须解锁水平。我已经找到了代码（或者我相信），但是当它声明级别被解锁时，它不会让你选择它。 （我是初学者，请应对我糟糕的编程知识）这是我的代码：
我遇到问题的地方在这里：
def the_game(difficulty_name, range_start, range_end):
....
if score <= 5:
isCustomUnlocked = True
print ("You unlocked the Custom range!")
打印出＆＃34;自定义已解锁＆＃34;，但实际上并未解锁位于此处的自定义范围：
def main():
...
if isCustomUnlocked == True:
if choice == 6:
cls()
show_loading
答案 0 :(得分：4)
您在此设置isCustomUnlocked：
if score <= 5:
isCustomUnlocked = True
但是，由于您处于函数中，因此设置局部变量，而不是全局变量。将global isCustomUnlocked添加到您的函数开头：
def the_game(difficulty_name, range_start, range_end):
global isCustomUnlocked
# ...
有关详细信息，请参阅Using global variables in a function other than the one that created them。但是，为此创建一个类将产生更好的代码。
答案 1 :(得分：2)
在这里，我通常不会这样做。
如上所述，您在函数中设置isCustomUnlocked。我查看了你的代码并冒昧地改进了它。你应该考虑降低睡眠时间。并尽可能重用代码。
阅读格式化一点点和python，但总体来说我觉得它对初学者来说很好。
当脚本要求用户选择级别时，您可能希望使用提示重写逻辑。如果回答太快，则会收到错误消息，因为var未定义。
另外：考虑使用IDE进行开发，我推荐使用pyCharm。由于突出显示，你会在几秒钟内发现错误。
