Lesson 8 of 19
Tuples & Sets
Choose collections for fixed values and unique values.
Introduction
Tuples are ordered collections that should not change. Sets hold unique values and make membership checks simple.
Pick a tuple for a fixed record and a set when duplicates should disappear.
Key insight
Choose collections for fixed values and unique values.
Example
coordinates = (27.7, 85.3)
tags = {"python", "web", "python"}
print(coordinates, tags)This example shows the core tuples & sets idea in a small, runnable program.
Real-world example
Sets help remove duplicate tags from imported data.
