Matching Sequences and Mappings

Destructure lists and dicts.

Patterns That Destructure

The real power of match is destructuring. Sequence and mapping patterns let you check the shape of data and pull values out at the same time.

A sequence pattern in square brackets matches a list or tuple of that exact length, binding each element to a name.

point = [3, 4]

match point:
    case [x, y]:
        print('x =', x, 'y =', y)
