closed_range()

Create a closed range for a case: both start and stop are included.

Usage

Source

closed_range(
    start,
    stop,
    step=1,
)

With the default step of 1, closed_range(1, 5) covers 1, 2, 3, 4, 5 — unlike range(1, 5), the upper bound is part of the range. With a larger step the range never goes past stop: closed_range(1, 6, 2) covers 1, 3, 5, and stop itself is included when the step lands on it exactly, as in closed_range(1, 7, 2) -> 1, 3, 5, 7.

    with switch(value) as s:
        s.case(closed_range(1, 5), lambda: "1-to-5")
        s.case(closed_range(6, 7), lambda: "6-or-7")
        s.default(lambda: 'default')

Parameters

start: int

The inclusive lower bound of the range.

stop: int

The inclusive upper bound of the range.

step: int = 1

The step size between elements; must be 1 or greater (defaults to 1).

Returns

range

A range object with a closed (inclusive) upper bound.

Raises

ValueError

If start is not less than stop, or step is less than 1.
