Tuples are used for multiple values inside one variable. They are denoted with parentheses.

coordinates = (40, -40)

If you want to break them apart, you can use bracket notation and index in.

print(coordinates[0])
print(coordinates[1])

You can also unpack them into distinct variables.

latitude, longtiude = coordinates

Tuples do not support item assignment.

coordinates[0] = -42.376 # crash

Tuples are also more memory efficient.
