Python split () Black Magic

Split () Usage:

#!/usr/bin/pythonstr = "Line1-abcdef \nline2-abc \nline4-abcd";p rint str.split ();p rint str.split (', 1);

　　

The result of the above example output is as follows:

['line1-abcdef ',' line2-abc ',' LINE4-ABCD '][' Line1-abcdef ',  ' \nline2-abc \nline4-abcd ']

Points:

1. Using split () without parameters, it treats all spaces (space characters, tabs, newline characters) as delimiters.

2.filter (None, S.split ("))

A = ' hello++world!+ '   #如何取得 ' hello ' and ' world '? >>>a.split (' + ') [' Hello ', ' ', ' world! ', ']    #含有两个空字符串 >>>filter (None, A.split (' + ')) [' Hello ', ' World! ']
