【python】sorted函数出现TypeError: ‘＜‘ not supported between instances of ‘str‘ and ‘int‘

 

1. Problem

The following code:

self.cams = sorted(list(cam_set))

 Even if the int or str type conversion has been performed, the following error still occurs:

TypeError: '<' not supported between instances of 'str' and 'int'
