python-regexHow to count matches with Python regex?

Python regex can be used to count matches in a string. To do this, the re.findall() function can be used. This function returns a list of all matches in the string.

Example code

import re

string = "This is a string with some words"

matches = re.findall(r"\w+", string)

print(matches)

Output example

['This', 'is', 'a', 'string', 'with', 'some', 'words']

Code explanation

• import re: imports the re module which contains the findall() function
• re.findall(r"\w+", string): uses the findall() function to find all matches of the regex pattern \w+ in the string
• print(matches): prints the list of matches
