First, function description

1. Split () function

Syntax: str.split (str= "", num=string.count (str)) [n]

Parameter description:

Str: represents as a delimiter, defaults to a space, but cannot be empty (''). If there is no delimiter in the string, the entire string is taken as an element of the list

Num: indicates the number of splits. If there is a parameter num, it is only separated into num+1 substrings, and each substring can be assigned to a new variable

[n]: indicates that the nth slice is selected

Note: when using spaces as delimiters, items that are empty in the middle are automatically ignored

2. Os.path.split () function

Syntax: os.path.split ('PATH')

Parameter description:

PATH refers to the full path of a file as a parameter:

If a directory and file name are given, the output path and file name

If a directory name is given, the output path and empty file name

II. Examples

1. Example 1 shows how to use the split () function.

#! / usr/bin/python#-*-coding: UTF-8-*-str = "Line1-abcdef\ nLine2-abc\ nLine4-abcd"; print str.split (); # is delimited by spaces, including\ nprint str.split (', 1); and # is separated by spaces into two

The output of the above example is as follows:

['Line1-abcdef',' Line2-abc', 'Line4-abcd'] [' Line1-abcdef','\ nLine2-abc\ nLine4-abcd']

2. Example 2, with the # sign as the separator, specify the second parameter as 1, and return two parameter lists.

#! / usr/bin/python#-*-coding: UTF-8-*-txt = "Google#Runoob#Taobao#Facebook" # the second parameter is 1 and returns two parameter lists x = txt.split ("#", 1) print x

The output of the above example is as follows:
