5.3.1 The Random Number Generator Interface

The Random Number Generator interface describes the methods which are available for all random number generators. This will be enhanced in future releases of Python.

In this release of Python, the modules `random`, `whrandom`, and instances of the `whrandom.whrandom` class all conform to this interface.

`choice` (seq)
  Chooses a random element from the non-empty sequence seq and returns it.

`randint` (a, b)
  Deprecated since release 2.0. Use `randrange()` instead.

  Returns a random integer N such that `a <= N <= b`.

`random` ()
  Returns the next random floating point number in the range [0.0 ... 1.0).

`randrange` ([start,] stop[, step])
  Return a randomly selected element from `range(start, stop, step)`. This is equivalent to `choice(range(start, stop, step))`. New in version 1.5.2.

`uniform` (a, b)
  Returns a random real number N such that `a <= N < b`.
