Regular Expressions in Python | Scenario - Finding sub-string match patterns to validate a genuine number from a numeric string using Regular Expressions and search() method in Python | Conceptual Infographic Note

Case 01 : Ascertaining a positive match using "\w" to match a specific phone number to a generic string

Case 02 : Ascertaining a negative match or mismatch using "\w" whether a match over given string occurs or not
