    This function returns random bytes from an OS-specific randomness source.  The
    returned data should be unpredictable enough for cryptographic applications,
    though its exact quality depends on the OS implementation.  On a Unix-like
-   system this will query /dev/urandom, and on Windows it will use CryptGenRandom.
-   If a randomness source is not found, :exc:`NotImplementedError` will be raised.
+   system this will query ``/dev/urandom``, and on Windows it will use

    For an easy-to-use interface to the random number generator
    provided by your platform, please see :class:`random.SystemRandom`.
