pyqt5中的Python代码输出错误的值

如何解决pyqt5中的Python代码输出错误的值

这是下载ui文件的github链接 https://github.com/AbhiTheGreat75/so-pyqt5

此代码的主要问题是，当我单击带有股票名称的按钮时，它将使用错误的股票名称打开它。 如何复制： 因此，当您单击运行并运行代码时， 单击侧面的按钮之一 将会有一个打印语句，告诉您单击的夹心按钮 问题是打印语句和您单击的按钮不匹配

解决方法

好的，我找到了答案 由于某些原因，您不能在pyqt5中使用lambda 相反，您使用像这样的部分

from functools import partial
partial(func_name,arg1,arg2)
