Python indentation error:
我已经尝试过notepad ++和eclipse但是即便如此，它在第18行显示了一个缩进错误。我不知道，为什么它会给我一个像这样的错误......？ 请帮我。

在这种情况下，使用
-t : issue warnings about inconsistent tab usage (-tt: issue errors)
这将有助于查找由意外使用的标签引起的缩进问题。
排
1 | self.verticalLayout.addWidget(self.lineEdit) |
应该在其他行的同一级别上。
您可能会错过它，因为您的编辑器混合了制表符和空格。
如果您在自己的问题中单击"编辑"，您将看到此行未正确缩进。
这是你的报价，例如在线：
1 | self.lineEdit.setText(’My Generic Device Name’) |
试试这个：

看起来你使用了错误的单引号。 您需要使用
不确定这是不是你的问题。
