Python中的缩进错误导致语法错误

我在编译时遇到了这个错误。我知道为什么会发生这种情况，但由于我是新手，所以找不到解决方法。这个问题发生在生产线上 这是第二次编辑

文件“check.py”，第34行

缩进错误：应为缩进块

如果要从try块返回False，则需要将try块放在函数内部。TestFunction将测试图像是否良好，并返回True或False。如果TestFunction返回True，则继续下一步，否则打印错误消息并中断或退出。

这与缩进无关。您的代码中没有任何函数，那么您希望从中返回什么呢？您有一个

返回

，但是您确实为您展示的代码定义了一个函数吗？这实际上不是缩进问题。你认为

return

有什么作用？你想用

return

在

内部实现什么，除了
块之外？是的，我有，但我没有把它放在这里
