Python--strip,split,join

Strip function prototypes

declaration : S is a string, RM is a sequence of characters to be deleted

S.strip (RM) Remove the characters from the beginning and end of the s string in the RM delete sequence

S.lstrip (RM) Delete the character in the S string at the beginning of the RM delete sequence

S.rstrip (RM) Removes the character from the end of the S string that is located in the RM delete sequence

Note :

1. When RM is empty, the default is to remove the whitespace characters (including ' \ n ', ' \ R ', ' \ t ', ')

For example:

2. The RM delete sequence here is deleted as long as the character on the edge (beginning or end) is within the delete sequence.

For example:

Split function prototype

First, about the split and join methods

1 is processed only for strings. Split: Split string, join connection string
2.string.join (Sep): Combines all elements of Sep (string representations) into a new string, using string as a separator
3.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.

4. Os.path.splie ()/os.path.join () on the Import OS module seems to be a different processing mechanism, but functionally identical.
