Regular expressions in Python

Regular expressions in Python

Regular expressions are used to search for and manipulate patterns in text. Here's an example of using regular expressions to match a phone number:

python

import re

pattern = r"\d{3}-\d{3}-\d{4}"

text = "Call me at 123-456-7890"

match = re.search(pattern, text)

if match:

    print("Phone number found:", match.group())

else:

    print("Phone number not found.")

In this example, we import the re module to use regular expressions. We define a pattern that matches a phone number in the format "###-###-####". We then search for the pattern in the string "Call me at 123-456-7890" using the search function. If a match is found, we print the phone number. Otherwise, we print a message indicating that no phone number was found.
