Slicing in Python is a feature that enables accessing parts of sequences like strings, tuples, and lists. You can also use them to modify or delete the items of mutable sequences such as lists. Slices can also be applied to third-party objects like NumPy arrays, as well as Pandas series and data frames.
Slicing enables writing clean, concise, and readable code.
This article shows how to access, modify, and delete items with indices and slices, as well as how to use indexing.
This video is based on the article of our teammate Mirko.
