使用pygame在python中创建一个简单的按键检查​​器

Question

我正在使用pygame为gui在python中创建一个messenger应用程序。我试图检测按键，但我使用的代码很多，我不喜欢它，我想知道是否有更好的方法来检查哪些键按下然后发送那是一个字符串变量。

我的代码：

            if event.key == pygame.K_q:
                self.CharKeyPressed = "q"

                self.CharKeyPressed = "w"

对于大多数情况，您只需使用unicode事件的KEYDOWN属性：

self.CharKeyPressed = event.unicode
