Mastering Iteration Tools
Python treats many data collections as ordered sequences. The most common are lists (mutable), tuples (immutable), and strings (immutable). You learned in how to iterate through a sequence item by item in a loop. Loops over sequences are so essential to modern idiomatic (or “Pythonic,” as further explained in ) programming that the language provides a family of iteration tools that hide low-level loop bookkeeping and help you write clear, efficient programs.
Being Pythonic | |
|---|---|
 | The adjective “Pythonic” refers to Python code that follows the language’s idioms, philosophy, and design principles, rather than just using Python’s syntax to write code that resembles another language. It emphasizes readability, simplicity, and the use of built-in features effectively to write clear, efficient, and maintainable programs. |
