range

Construct a range, starting at 0 (inclusive), ending at end (exclusive), with a step size of 1.

Examples:

• list(range(0)) returns [].

• list(range(1)) returns [0].

• list(range(2)) returns [0, 1].

• list(range(10)) returns [0, 1, 2, 3, 4, 5, 6, 7, 8, 9].

Note that range(x) is equivalent to range(0, x, 1).

Parameters

Throws

Construct a range, starting at start (inclusive), ending at end (exclusive), with a "step size" (i.e. difference between consecutive values) of step.

If start > end, then step must be negative. Conversely, if start < end, the step must be positive. step cannot be 0.

Examples:

• list(range(1, 23, 3)) returns [1, 4, 7, 10, 13, 16, 19, 22].

• list(range(20, 1, -2)) returns [20, 18, 16, 14, 12, 10, 8, 6, 4, 2].

• list(range(-2, -8, -1)) returns [-2, -3, -4, -5, -6, -7].

• list(range(3, 3, 7)) returns []. Indeed, for all x, and for all y != 0, range(x, x, y) returns [].

Note that range(0, x, 1) is equivalent to range(x).
