Tuples
Immutable ordered sequences — great for fixed records and returning several values.
Beginner
point = (10, 20)
x, y = point # unpacking
def min_max(values):
return min(values), max(values) # returns a tuple
low, high = min_max([3, 9, 1])
Because tuples can't change, they can be used as dictionary keys and signal "this data is fixed".
