Python Regular Expressions Masterclass: Ultimate Guide to Regular Expressions & re Module Functions


Welcome to the definitive Introduction to Regular Expressions (RegEx) in Python! RegEx is an invaluable skill for any programmer, essential for advanced string processing, data validation, and powerful text extraction.

This video demystifies the Python re module and teaches you how to leverage its pre-defined functions for massive text manipulation power.

What You Will Master:

RegEx Fundamentals: Understanding patterns, metacharacters, and raw strings (r'...').

The re Module's Core Functions:
1. re.match(): Check for a pattern match only at the start of a string.
2. re.search(): Scan through a string to find the first location where the pattern matches.
3. re.findall(): Find all non-overlapping matches and return them as a list.
4. re.sub(): Find a pattern and replace it with a specified replacement string.

Special Sequences & Shorthands: Using \d (digits), \w (word characters), and \s (whitespace).
Quantifiers and Sets: Mastering +, *, ?, and character sets [...].
Practical Programs: Code along as we build examples for email validation, phone number extraction, and data cleaning.
