""" Random numbers. MicroPython module: https://docs.micropython.org/en/v1.26.0/library/random.html This module implements a pseudo-random number generator (PRNG). CPython module: :mod:`python:random` https://docs.python.org/3/library/random.html . . .. note:: The following notation is used for intervals: - () are open interval brackets and do not include their endpoints. For example, (0, 1) means greater than 0 and less than 1. In set notation: (0, 1) = {x | 0 < x < 1}. - [] are closed interval brackets which include all their limit points. For example, [0, 1] means greater than or equal to 0 and less than or equal to 1. In set notation: [0, 1] = {x | 0 <= x <= 1}. .. note:: The :func:`randrange`, :func:`randint` and :func:`choice` functions are only available if the ``MICROPY_PY_RANDOM_EXTRA_FUNCS`` configuration option is enabled. --- Module: 'random' on micropython-v1.26.0-rp2-RPI_PICO """ # MCU: {'mpy': 'v6.3', 'build': '', 'ver': '1.26.0', 'arch': 'armv6m', 'version': '1.26.0', 'port': 'rp2', 'board': 'RPI_PICO', 'family': 'micropython', 'board_id': 'RPI_PICO', 'variant': '', 'cpu': 'RP2040'} # Stubber: v1.26.0 from __future__ import annotations from _typeshed import Incomplete from _mpy_shed import Subscriptable from typing import overload from typing_extensions import Awaitable, TypeAlias, TypeVar _T = TypeVar("_T") @overload def randrange(stop: int, /) -> int: """ The first form returns a random integer from the range [0, *stop*).
