If you can't, try with crng:

NAME
    crng - Random-number generators implemented as C extension types.

FILE
    /usr/lib/python2.2/site-packages/crng.dll

DESCRIPTION
    The generators are uniform in the open interval (0.0,1.0).
    Instance objects are callable; calls are equivalent to the 'next'
method.

        Random-number generator types
    ParkMiller    -- Park-Miller 'minimal standard'
    WichmannHill  -- Wichmann-Hill portable RNG (algorithm AS 183)
    LEcuyer       -- Pierre L'Ecuyer's MLCG of 1988
    Ranlux        -- Martin Luescher's RANLUX
    Taus88        -- three-component combined Tausworthe RNG by
L'Ecuyer
    MRG32k3a      -- combined multiple recursive 32-bit RNG by
L'Ecuyer
    MT19937       -- Mersenne Twister by Matsumoto and Nishimura
