EDA Python - 07-2Stringmethods

The video tutorial introduces F-strings in Python, demonstrating how to format strings and include calculations. It covers various string methods like upper, lower, title, split, and strip, which are useful in data analysis. The tutorial also explains string slicing, showing how to access specific characters or ranges within a string using indexing and steps.
