Return a tuple representing the internal state of the generator.
For more details, see set_state.
out : tuple(str, ndarray of 624 uints, int, int, float)
The returned tuple has the following items:
- the string ‘MT19937’.
- a 1-D array of 624 unsigned integer keys.
- an integer pos.
- an integer has_gauss.
- a float cached_gaussian.
set_state and get_state are not needed to work with any of the random distributions in NumPy. If the internal state is manually altered, the user should know exactly what he/she is doing.
