Question

我有这两个脚本。首先包含使用pyqt5的ui，其中包含一些文本框和按钮。第二个包含按钮的功能（我是说它会做什么）。现在，我只想在终端中显示文本框中的内容。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（上载按钮），单击时必须在终端中显示此文本。

我尝试将第二个py导入到第一个。然后我连接按钮。 butUpld.clicked.connect（py2.up）

对于第二个py，我也将其连接到第一个

This is the first py file name py1.py

this the second py file named py2.py

import os, glob
import py1

def up():
    a = gui.rep.tab1U.tboxEV
    print(a.text())

尝试一下：
