split() The method can be divided according to a specified string delimiter into a plurality of sub-strings, the string will be saved to the sub-list (excluding separator)
split() Method syntax:str.split(sep,maxsplit)
str : the string to be split
On Sep : specifies the separator may comprise a plurality of characters (e.g., '1<>2<>3'.split('<>')returns ['1', '2', '3']). This parameter defaults None, showing all blank characters, including spaces, newline \ n-, tab \ t like
maxsplit is : an optional parameter that specifies the number of division (and therefore, there will be a list of most elements maxsplit + 1), if not specified, or specified as -1 indicates that the number of divisions is not limited.
For example:
>>> '1 2 3 4'.split()
['1', '2', '3', '4']
>>> '1,2,3'.split(',')
['1', '2', '3']
>>> '1,2,3'.split(',', 1)
['1', '2,3']
>>> '1,2,,3,'.split(',')
['1', '2', '', '3', '']
>>> '1<<20<<300'.split('<<')
['1', '20', '300']
The special little, if no sepparameter, when there is a continuous string of blank spaces or other characters, will be treated as a string delimiter is divided
>>> '1 2 3 4 5'.split()
['1', '2', '3', '4', '5']
