python-regexHow to extract found values with Python regex?

Python regex can be used to extract found values from a string. The re.findall() function can be used to find all matches in a string and return them as a list.

Example code

import re

string = "The cat in the hat"

matches = re.findall("cat", string)

print(matches)

Output example

['cat']

Code explanation

• import re: imports the Python regex module
• string = "The cat in the hat": assigns the string to be searched
• matches = re.findall("cat", string): uses the re.findall() function to search for the pattern "cat" in the string and assign the matches to the matches variable
• print(matches): prints the matches found
