TRIQS exposes to python the random number generators used in C++,
in the module ``RandomGenerator``.
The generators are the boost random generators.

Then you can either generate float number on the interval :math:`[0,1[`
simply by calling the generator, or integer numbers in the inverval :math:`[0,N-1]` by calling
it with `N` ::
