Module 06
String Handling
Learn string operations, methods, examples, and problem-solving patterns.
01
String Handling Overview
Review indexing, slicing, and immutability of str, then understand the built-in string methods through visual diagrams.
02
Case Conversion Methods
Learn capitalize(), title(), upper(), lower(), and swapcase() with visual syntax, memory tricks, and transformation flows.
03
String Validation Methods
Learn how to validate strings using isupper(), islower(), isalpha(), isdigit(), isalnum(), and isspace() with visual decision flows.
04
index() and count()
Learn how to locate the position of a substring with index() and count occurrences with count() using visual diagrams and memory tricks.
05
lstrip(), rstrip(), and strip()
Learn how to remove spaces and unwanted characters from the left, right, or both ends of a string using visual memory diagrams.
06
split() and join()
Learn how to break a string into a list with split() and rebuild it into a string using join() through visual diagrams and real-world examples.
07
startswith() and endswith()
Learn how to verify whether a string begins or ends with specific text using visual memory diagrams and real-world validation examples.
08
String Methods — Practice Programs
Build real programs by combining split(), join(), strip(), case conversion, and validation methods. Focus on method chaining and practical data cleaning.
