About the split and join methods of string Os.path.splie ()/os.path.join () for importing OS modules seems to be a different processing mechanism, but functionally identical. 1.string.split (str= ", Num=string.count (str)): delimited by str, the character slices a string, and if NUM has a specified value, only the NUM substring is delimited. S.split ([Sep [, Maxsplit]])-a list of strings separated by a string that returns a list of delimited (Sep)

There is no character type in Python, only a string, the character here is a string that contains only one character!!!The reason for writing here is just for the convenience of understanding, that's all.1. Divide a string by one delimiter:>>> str ="My name is Liu de Hua">>>Str'My name is Liu de Hua'>>> split_str = Str.split (' ')>>>Printsplit_str['my','name',' is','Liu','de','Hua']>>>2.

Strip function prototype Declaration: S is a string, RM is the sequence of characters to be deleted. You can only delete characters or strings that start or end. The middle character or string cannot be deleted. S.strip (RM) deletes the character at the beginning and end of the s string that is in the RM delete sequence S.lstrip (RM) deletes the character at the beginning of the S string at the RM delete sequence S.rstrip (RM) deletes the character at the end of the S string that is in the RM de
