python-regexHow to match any letter with Python regex?

To match any letter with Python regex, you can use the \w character class. This character class will match any alphanumeric character, including both upper and lowercase letters.

Example code

import re

pattern = re.compile(r'\w')

string = 'Hello World!'

matches = pattern.findall(string)

Output example

['H', 'e', 'l', 'l', 'o', 'W', 'o', 'r', 'l', 'd']

Code explanation

• import re: imports the re module, which contains the functions needed for regular expression matching
• pattern = re.compile(r'\w'): compiles the regular expression pattern \w, which matches any alphanumeric character
• string = 'Hello World!': sets the string to be matched
• matches = pattern.findall(string): finds all matches of the pattern in the string
