Lesson 11 / 49
Tuples
Group fixed values with immutable tuples, unpack them and avoid the one-item tuple comma trap.
Immutable by design
A tuple looks like a list but can't be changed after creation. Use it for data that shouldn't move.
point = (10, 20)
name, age = ("Ada", 36) # unpacking
print(point[0]) # 10
# point[0] = 99 # TypeErrorThe trailing comma trap
A one-item tuple needs a trailing comma: single = (5,) — without it, (5) is just the int 5.
