Understanding Regex Patterns

Regex has numerous applications, including data validation, text processing, and data extraction. For example, you can use regex to validate phone numbers or credit card numbers. You can also use regex to extract numbers from a string. The regex pattern \d+ can be used to extract all numbers from a string, while the regex pattern \d* can be used to extract all substrings that may or may not contain numbers. By using regex, you can simplify complex string processing tasks and improve the efficiency of your code.
