python和pyqt5-单击按钮后传递变量

标签: python variables button pyqt5

我有2个py文件:my.py(这是我从ui创建的py-我有窗口和输入行,按钮的脚本)和vat.py(这是第二个脚本,单击pushButton_2时需要启动)。我想从增值税脚本运行所有行,但是my.py需要将一些变量传输到vat.py。这是一个问题-我该怎么做?

from my import *
print(glob)
#imp = Ui_MainWindow.setupUi.__getattribute__(lineEdit.text()) - dosent work

一切看起来都很好,但是当我运行my.py并单击button2时(如您所见,我正在从行编辑获取路径),此操作无效。我在vat.py脚本中看到“ glob = empty”。当然,vat.py文件具有更多功能和执行某些操作,但是我需要从vat.py文件进行所有步骤(但是我需要传递一些变量。当vat完成所有步骤时,是否还可以将vat反馈给我? TIA

您需要在vat.py中创建一个函数并将代码移入其中。这样,您可以在脚本顶部导入该函数,但仅在需要时调用它。您也可以多次调用它(与导入不同)。当然,您可以将参数传递给函数。

vat.py类似于:

def vat(glob):
    print(glob)

然后在my.py中,您可以执行以下操作:

from vat import vat

vat(glob)
