Python Coding challenge - Day 130 | What is the output of the following Python Code?

 

Codes: 

import re

x = re.compile(r'\W')

y = x.findall('clcoding')

print(y)

Answer and Solution:

In the above Python code, the re module to create a regular expression pattern and then using it to find all non-word characters in the string 'clcoding'. The regular expression pattern r'\W' matches any non-word character (equivalent to [^a-zA-Z0-9_]).

Here's a breakdown of the code:

import re: Imports the regular expression module.

x = re.compile(r'\W'): Compiles a regular expression pattern \W, where \W matches any non-word character.

y = x.findall('clcoding'): Uses the compiled regular expression to find all non-word characters in the string 'clcoding' and stores the result in the variable y.

print(y): Prints the result, which is a list of non-word characters found in the string.

In the given example, since the string 'clcoding' contains only letters (no non-word characters), the output will be an empty list []. If there were non-word characters in the string, they would be included in the list.
