Splitting and Slicing
join()
Parameters
string.join(iterable)
iterable*: a python iterable e.g a list, tuple, string, dictionary or set.
Return value
Returns a string concatenated with the elements of the passed in iterable.
Example
Python 3.7.4
>>> n1 = ['1', '2', '3', '4', '5']
>>> n2 = ('1', '2', '3', '4', '5')
>>> separator = ', '
>>> separator.join(n1)
'1, 2, 3, 4, 5'
>>> separator.join(n2)
'1, 2, 3, 4, 5'
partition()
Parameters
string.partition(separator)
separator*: the part of the string that will trigger the separation. If it occurs more than once in the string, the first occurrence is considered.
Return value
Return a tuple containing three parts:
- the part of the string before the separator
- the separator itself
- the part of the string after the separator
Example
Python 3.7.4
>>> s = "I feel the need - the need for speed!"
>>> s.partition("-")
('I feel the need ', '-', ' the need for speed!')
>>> s.partition(",")
('I feel the need - the need for speed!', '', '')
>>> s = "I feel the need - the need - for speed!"
>>> s.partition("-")
('I feel the need ', '-', ' the need - for speed!')
rpartition()
Parameters
string.rpartition(separator)
separator*: the part of the string that will trigger the separation. If it occurs more than once in the string, the last occurrence is considered.
Return value
Return a tuple containing three parts:
- the part of the string before the last occurrence of the separator
- the separator itself
- the part of the string after the separator
Example
Python 3.7.4
>>> s = "I feel the need - the need for speed!"
>>> s.rpartition("-")
('I feel the need ', '-', ' the need for speed!')
>>> s.rpartition(",")
('', '', 'I feel the need - the need for speed!')
>>> s = "I feel the need - the need - for speed!"
>>> s.rpartition("-")
('I feel the need - the need ', '-', ' for speed!')
split()
Parameters
string.split(separator, maxsplit)
separator: the element to use in separating the string. If none is specified, the string is separated using spaces.
maxsplit: the maximum number of splits
Return value
Returns a list of strings separated at the specified separator.
Example
Python 3.7.4
>>> s = "I feel the need - the need for speed!"
>>> s.split()
['I', 'feel', 'the', 'need', '-', 'the', 'need', 'for', 'speed!']
>>> s.split("-")
['I feel the need ', ' the need for speed!']
>>> s.split("need")
['I feel the ', ' - the ', ' for speed!']
>>> s.split("need", 1)
['I feel the ', ' - the need for speed!']
rsplit()
Parameters
string.rsplit(separator, maxsplit)
separator: the element to use in separating the string. If none is specified, the string isseparated using spaces.
maxsplit: the maximum number of splits
Return value
Returns a list of strings separated at the specified separator starting from the right.
Example
Python 3.7.4
>>> s = "I feel the need - the need for speed!"
>>> s.rsplit()
['I', 'feel', 'the', 'need', '-', 'the', 'need', 'for', 'speed!']
>>> s.rsplit("-")
['I feel the need ', ' the need for speed!']
>>> s.rsplit("need")
['I feel the ', ' - the ', ' for speed!']
>>> s.rsplit("need", 1)
['I feel the need - the ', ' for speed!']
splitlines()
Parameters
string.splitlines(keepends)
keepends: if included, the line breaks are also included in the returned items of the list.Provided as either True or False. Defaults to False if nothing is provided.
Return value
Returns a list of lines in the string.
Example
Python 3.7.4
>>> s = """“Hope” is the thing with feathers -
... That perches in the soul -
... And sings the tune without the words -
... And never stops - at all -"""
>>> s.splitlines()
['“Hope” is the thing with feathers -', 'That perches in the soul -',
'And sings the tune without the words -', 'And never stops - at all -']
>>> s.splitlines(True)
['“Hope” is the thing with feathers -\n', 'That perches in the soul -\n',
'And sings the tune without the words -\n', 'And never stops - at all -']
