Python Tip: Tuple Unpacking for Multiple Assignments

Assigning multiple variables at once from a sequence can be done elegantly using tuple unpacking (also known as sequence unpacking). It's clean and efficient.

Traditional way:

coordinates = (10, 20)
x = coordinates[0]
y = coordinates[1]
print(f"X: {x}, Y: {y}")

Using Tuple Unpacking:

coordinates = (10, 20)
x, y = coordinates
print(f"X: {x}, Y: {y}")

This also works with lists and functions that return multiple values. It's often used for swapping variables without a temporary variable:

a = 5
b = 10
a, b = b, a # Swaps values of a and b
print(f"a: {a}, b: {b}") # Output: a: 10, b: 5
