Split string on whitespace in Python
PythonRegexStringSplitWhitespacePython Problem Overview
I'm looking for the Python equivalent of
String str = "many fancy word \nhello \thi";
String whiteSpaceRegex = "\\s";
String[] words = str.split(whiteSpaceRegex);
["many", "fancy", "word", "hello", "hi"]
Python Solutions
Solution 1 - Python
The str.split() method without an argument splits on whitespace:
>>> "many fancy word \nhello \thi".split()
['many', 'fancy', 'word', 'hello', 'hi']
Solution 2 - Python
import re
s = "many fancy word \nhello \thi"
re.split('\s+', s)
Solution 3 - Python
Using split() will be the most Pythonic way of splitting on a string.
It's also useful to remember that if you use split() on a string that does not have a whitespace then that string will be returned to you in a list.
Example:
>>> "ark".split()
['ark']
Solution 4 - Python
Another method through re module. It does the reverse operation of matching all the words instead of spitting the whole sentence by space.
>>> import re
>>> s = "many fancy word \nhello \thi"
>>> re.findall(r'\S+', s)
['many', 'fancy', 'word', 'hello', 'hi']
Above regex would match one or more non-space characters.
