Python String split() method in Python split a string into a list of strings after breaking the given string by the specified separator.
Python String split() Method Syntax
Syntax : str.split(separator, maxsplit)
Parameters :
- separator: This is a delimiter. The string splits at this specified separator. If is not provided then any white space is a separator.
- maxsplit: It is a number, which tells us to split the string into maximum of provided number of times. If it is not provided then the default is -1 that means there is no limit.
Returns : Returns a list of strings after breaking the given string by the specified separator.
Python String split() Method Example
Python3
string = "one,two,three"words = string.split(',')print(words) |
Output:
['one', 'two', 'three']
Time Complexity: O(n)
Auxiliary Space: O(n)
How split() works in Python?
Here we are using the Python String split() function to split different Strings into a list, separated by different characters in each case.
Python3
text = 'geeks for geeks' # Splits at spaceprint(text.split()) word = 'geeks, for, geeks' # Splits at ','print(word.split(',')) word = 'geeks:for:geeks' # Splitting at ':'print(word.split(':')) word = 'CatBatSatFatOr' # Splitting at tprint(word.split('t')) |
Output :
['geeks', 'for', 'geeks'] ['geeks', ' for', ' geeks'] ['geeks', 'for', 'geeks'] ['Ca', 'Ba', 'Sa', 'Fa', 'Or']
Time Complexity: O(n)
Auxiliary Space: O(n)
How does split() work when maxsplit is specified?
The maxsplit parameter is used to control how many splits to return after the string is parsed. Even if there are multiple splits possible, it’ll only do maximum that number of splits as defined by maxsplit parameter.
Python3
word = 'geeks, for, geeks, pawan' # maxsplit: 0print(word.split(', ', 0)) # maxsplit: 4print(word.split(', ', 4)) # maxsplit: 1print(word.split(', ', 1)) |
Output :
['geeks, for, geeks, pawan'] ['geeks', 'for', 'geeks', 'pawan'] ['geeks', 'for, geeks, pawan']
Time Complexity: O(n)
Auxiliary Space: O(n)
