python - openCV中的Mac警报弹出窗口

Question

我试图让mac弹出窗口使用applescript为我的小openCV项目工作，但我似乎无法让它工作，我已经评论了它是如何在windows中完成的，但我的返回值不断出现无效的语法错误苹果脚本

您在定义 returnValue 时遇到语法错误.

你的代码:

returnValue = applescript """
    display dialog"""+(None,self.name,self.type, 1)"""
    with title "this is a mac pop up""
    with icon caution 
    buttons  {"OK"}
    """

它缺少一些导致您的语法错误的连接。它应该是这样的:

returnValue = applescript + """
    display dialog"""+(None,self.name,self.type, 1)+"""
    with title "this is a mac pop up""
    with icon caution 
    buttons  {"OK"}
    """

此外，这种带括号的语法会导致更多错误。我不确定这些的意图究竟是什么，但我假设它用于将变量注入(inject)到字符串中，在这种情况下，您的最终代码将类似于以下内容:

returnValue = applescript + """
    display dialog "%s %s"
    with title "%s %s"
    with icon caution 
    buttons  {"OK"}
    """ % (None,self.name,self.type, 1)

您需要决定变量的去向以及需要如何格式化它们才能满足您的需求，但这至少应该能让您顺利上路。
