Regular expressions (regex) are powerful tools for pattern matching in strings. In Python, the re module provides functions like re.match(), re.search(), and re.findall() to work with regular expressions. Here are examples for each: 1. re.match(): re.match() checks for a match only at the beginning of the string: 2. re.search(): re.search() searches for the pattern anywhere…
