Python In Practice - 15 Projects to Master Python - String Built-In Functions

This video tutorial covers the use of built-in string methods in Python, focusing on methods accessible via the dot operator, such as capitalize, title, and swapcase. It also explores built-in functions like length and ord that do not use the dot operator, explaining how to determine string length and Unicode values. The tutorial provides practical examples and encourages viewers to explore additional string methods independently.
