Python BeautifulSoup [解决方法] TypeError: list indices must be integers or slices, not str
Integers and slices are both types of data in programming languages.
Integers are whole numbers, either positive, negative, or zero, that can be used for arithmetic operations or as variables to store numerical values. In Python, for example, integers are represented as int.
Slices, on the other hand, are a way to extract a portion of a sequence (such as a list or a string) by specifying a start and end index. In Python, for example, the syntax for slicing a list is myList[start:end], where start is the index of the first element to include and end is the index of the first element to exclude.
So, to summarize, integers are used for numerical calculations while slices are used for extracting portions of sequences.
