Python's str.rsplit(~) method splits up the string based on the specified separator, and returns a list containing the separated items. As opposed to str.split(~) which splits from the left, str.rsplit(~) splits from the right.

Parameters

1. sep | string | optional

The separator used to split up the string. By default, sep=" " (i.e. a single space).

2. maxsplit | number | optional

The maximum number of splits you want to make. By default, maxsplit=-1 (i.e. no maximum set).

Return value

A list of separated strings.

Examples

Sep parameter

By default, the separator used is a single white space:

x = "a b c"
x.rsplit()
['a', 'b', 'c']

To split by comma instead:

y = "a,b,c"
y.rsplit(",")
['a', 'b', 'c']

Sep does not exist in string

To split "abc" using comma as the separator:

z = "abc"
z.rsplit(",")
['abc']

We return a list with the original string as the sole element as the separator did not exist in the string.

Maxsplit parameter

To split "a,b,c" at most once:

w = "a,b,c"
w.rsplit(",", 1))
['a,b', 'c']

The splitting happens only once from the right despite the fact that we have two commas.
