在python中，我希望一个函数与我的普通脚本同时运行。我搜索了互联网并发现了线程，但是，当我实现它并运行代码时，出现了错误NameError: name 'datelabelstringvar' is not defined。我不知道出了什么问题，但是当我删除线程并将功能分配给按钮时(我不想只是清楚，我希望它是自动的(，它工作正常。
法典：

如何修复此错误？谢谢。
编辑： 完全错误：

NameError: name 'datelabelstringvar' is not defined
您的代码对datelabelstringvar变量进行了多次引用。 但是，您永远不会定义它。 这就是Python所说的。
编辑：
您似乎从未调用过定义变量的calendar函数。
