Python's str.partition(~) method splits the string at the first occurrence of the separator to return a tuple containing three elements: the part before the separator, the separator itself, and the part after the separator.

Parameters

1. sep | string

The string to use as the separator.

Return value

The return value depends on the following cases:

Case

Return value

Separator found in string

Tuple with three elements:

First element: part before the separator

Second element: the separator itself

Third element: part after the separator

Separator NOT found in string

Tuple with three elements:

First element: the string itself

Second element: empty string

Third element: empty string

Examples

Separator found in string

To split the string "Hello fellow SkyTowner!" at first occurrence of 'll':

x = "Hello fellow SkyTowner!"
x.partition('ll')
('He', 'll', 'o fellow SkyTowner!')
('He', 'll', 'o fellow SkyTowner!')

Note that we return a tuple containing the part before the separator ('He'), the separator itself ('ll') and the part after the separator ('o fellow SkyTowner!').

Separator NOT found in string

To split the string "Hello fellow SkyTowner!" at first occurrence of 'tt':

y = "Hello fellow SkyTowner!"
y.partition('tt')
('Hello fellow SkyTowner!', '', '')

As the separator 'tt' is not found in the string "Hello fellow SkyTowner!", we return a tuple containing the original string, and two empty strings.
