How do I write a Python regular expression to get zero or more occurrences of '\w' or word(an alphabet, digit or underscore) in the string 'chihua huahua'?
* An asterisk meta-character in a regular expression indicates 0 or more occurrences of the pattern to its left
The following code matches and prints the zero or more occurrences of the pattern '\w' in the string 'chihua huahua'
import re s = 'chihua huahua' result = re.findall(r'\w*', s) print result
This gives the output
['chihua', '', 'huahua', '']
