Lists — a row of things
P40.lists-and-tables.01 · Audience: guest, language-pro, it-ml · Prerequisites: Variables — naming things
Alphabetising a glossary by hand is slow, and easy to get wrong. Picture the paper task: a column of words you shuffle into order. This module gives you the code shape for that column — the list — and builds up to alphabetising it in one line.
ⓘ Concept: A list is an ordered row
["pear", "apple", "cherry"]. You keep lists everywhere — a class register, a reading list, a glossary — and Python writes one the same way each time.Why it matters — A word list, a register, a glossary — most of a language professional's material is a list. It is the container the rest of the discipline builds on.
