如果知道有帮助，我只需要存储整数、值，谢谢！ 问题所在代码的主要部分位于函数“zScore”下方的底部附近，但它确实使用了在整个代码中创建的一些类。任何帮助表示赞赏。

我最初尝试将变量文本存储在另一个变量中并使用此输入变量进行基本操作，但输入框当然只接受字符串。然后我尝试使用 int() 函数尝试将输入到输入框中的字符串转换为整数，但这也不起作用。我也无法在同一屏幕上使用多个输入框。

【问题讨论】：

我知道您正在使用我的示例，但您的问题中有很多代码，我们必须对其进行分析才能给出答案。如果您将其减少到 minimal, runnable example 将会很有帮助。

我的原始示例的链接：***.com/a/46390412/6220679

【参考方案1】：

您只需在用户按下回车键时将text 变量转换为int。这应该有效：

if event.key == pygame.K_RETURN:
    try:
        input1 = int(text)
    except ValueError:
        print('Invalid input')
    text = ""

【讨论】：

我不确定你想用 input1 做什么。如果你想在其他功能之一中使用它，你必须return它。

嗨，对不起，我刚刚看到你的评论。是的，这是你的算法，如果我应该先问的话，我很抱歉，你的帖子对我很有帮助。感谢您再次回复我的 pygame 问题，您非常有帮助！
