Python 如何使用另一个py脚本获取pyqt中文本框的输入

我有这两个脚本。首先包含使用pyqt5的ui，这包含一些文本框和按钮。第二个包含按钮的功能（我指的是它的功能）。现在我只想在终端上显示文本框中写的内容。问题是我无法使用第二个py在文本框中获取/打印/显示输入文本。我有这个按钮（上传按钮），当点击时，它必须在终端上显示这个文本

我已尝试将第二个py导入第一个py。然后我接上按钮。 butUpld.clicked.connect（py2.up）

对于第二个py，我还将其连接到第一个py

This is the first py file name py1.py

成功了！非常感谢。你能解释一下为什么把tboxEV=QLineEdit（self）改为self.tboxEV=QLineEdit（self），我是说区别。为什么要使用butUpld.clicked.connect（lambda，s=self:py2.up（s））而不仅仅是butUpld.clicked.connect（py2.up）@p\u p

self.tboxEV

-使

tboxEV

对象成为

Layoutexe

类的属性。因此，可以从另一个方法/函数访问

self.tboxEV

对象。

up

函数不知道

Layoutexe

对象是否存在，因此必须将其传递给此函数。一种方法是

butUpld.clicked.connect（lambda，s=self:py\uu 2.up））
