如何使用另一个py scrip获取pyqt中文本框的输入

Question

我有这两个剧本。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（我指的是它将做什么），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获取/打印/显示文本框中的输入文本。我有这个按钮（上传按钮），必须显示在终端点击时，这个文本。你知道吗

我试着将第二个py导入第一个py。然后我接上按钮。 butUpld.clicked.connect连接（py2.以上）

对于第二个py，我也将它连接到第一个py

This is the first py file name py1.py

this the second py file named py2.py

def up():

    print(a.text())
