为什么我运行的这个wxpython小程序界面打不开

这两个脚本是都应该没问题才对

我不知道你是怎么运行的。我是说这样，打开PythonWin. 然后在里面用execfile的方式来运行这个脚本。第一次没问题， 第二次再执行execfile就会出问题。 当然如果关掉PythonWin，再重新打开，然后运行，当然也没问题

以下是具体代码:

我用的Python2.7

需要在当前文件夹下创建script.py

按照你的要求做了个界面，调用clickButton函数处理你的逻辑，然后调用textbox的setvalue方法将你的结果写到文本框中

你觉得界面不合理的话，你可以自己调用layout和properties两个参数是界面参数
