Tuples

collection = single "variable" used to store multiple values
Tuple = () ordered and unchangeable (immutable). Duplicates allowed.
Faster and memory-efficient than lists. Good for fixed data.
Tuples are useful for:

• Returning multiple values from functions
• Storing related but unchangeable data (e.g., coordinates, RGB values)

Creating a tuple

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

Accessing items

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

print(fruits[1])           # Access by index → "apple"
print(fruits[-1])          # Last item → "apple"

Iterating

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

for fruit in fruits:
    print(fruit)

Count and index

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

print(fruits.count("apple"))   # → 2 (counts how many times "apple" appears)
print(fruits.index("orange"))  # → 2 (position of first "orange")

Length

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

print(len(fruits))             # → 5

Min/Max for strings

It does this lexicographically

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

print(min(fruits))             # → "apple"
print(max(fruits))             # → "watermelon"

Slicing

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

print(fruits[1:3])  # → ("apple", "orange")

Copying a tuple

Just assign since it's immutable

tuples.py

fruits = ("banana", "apple", "orange", "watermelon", "apple")

fruits_copy = fruits  # Both point to same tuple (safe because it can't be changed)
