Definition and usage
#The split() method splits a string into a list of fragments. Without an argument, it splits on any whitespace and skips empty fragments, so several spaces in a row do not create empty elements.
With an argument, it splits exactly where the separator occurs, for example a comma. Then two separators next to each other produce an empty string in the result.
The maxsplit parameter limits the number of splits, which is handy for data like "key=value=with=characters". The opposite of split() is join().
Syntax
#Syntax
string.split(sep=None, maxsplit=-1)Parameters
#sep
str, optional
The separator. Defaults to any whitespace.maxsplit
int, default -1
The maximum number of splits. -1 means no limit.
Good practices
#- For CSV files, use the
csvmodule. A manualsplit(",")will not handle commas inside quotes. - Unpacking the result with
name, score = line.split(",")only works when there are exactly two parts.
