Python Tutorial 4.2 - Tuples in Python

Welcome to the “Tuples in Python” tutorial!

Overview

Tuples are ordered, immutable sequences used to store heterogeneous data.

Creating Tuples

colors = ("red", "green", "blue")
single = (42,)  # single‑element tuple requires a comma
empty = ()

Tuple Operations

• Indexing & Slicing:

  print(colors[1])     # "green"
  print(colors[:2])    # ("red", "green")
  

• Immutability:
  Elements cannot be changed once assigned.

  # colors[0] = "yellow"  # Error!
  

• Packing & Unpacking:

  point = (10, 20)
  x, y = point
  

Key Takeaways

• Tuples provide data integrity with immutability.
• Use for fixed collections or as keys in dictionaries.
• Packing and unpacking enable clear multiple assignments.

Happy coding!
