Question

我试图在按钮点击上运行外部Python脚本。我认为我几乎有它工作，虽然它一旦我运行GUI类本身就运行外部脚本。单击按钮时我需要它来运行脚本。我想我几乎拥有它，有人可以指导我需要改变的地方。

我编写了一个名为parseCanonical（）的函数：这是我尝试设置按钮单击的位置，以便我可以运行外部脚本。

Answer 1

我认为os.system('CanonicalAddressesParser.py')不是您搜索的内容如果您的脚本CanonicalAddressesParser.py与主脚本位于同一文件夹中，则可以将其导入import CanonicalAddressesParser。
然后调用CanonicalAddressesParser内的函数，你需要写：CanonicalAddressesParser.func()

所以如果你替换

self.canonicalAddressesButton.clicked().connect(self.select_data())

通过

self.canonicalAddressesButton.clicked.connect(CanonicalAddressesParser.select_data)

有帮助吗？

Answer 2

一旦运行GUI就打开脚本的原因是你在retranslateUi函数下有这个调用os.system('CanonicalAddressesParser.py')，所以它和其他一切一起被调用。此外，您在未调用的函数内部设置按钮。按钮似乎连接到一个不存在的功能（或者至少不包含在您发布的代码中）。您还错误地设置了该按钮。您在其上方设置的按钮单击事件是正确的。

我建议创建一个名为select_data的函数，并将脚本运行行移动到该函数，然后从按钮调用它。

def retranslateUi(self, MainWindow):
    # Code here
    self.canonicalAddressesButton.clicked.connect(self.select_data)

def select_data(self):
    os.system('CanonicalAddressesParser.py')

单击按钮运行脚本
