random_generator

numpy's RandomState provides methods for generating random numbers (see RandomState's help for more information).

Note that all instances of subclasses of TransferFnWithRandomState will share this RandomState object, and hence its state. To create an instance of an TransferFnWithRandomState subclass that has its own state, set this parameter on the instance to a new RandomState instance.

Value:

__abstract

bool(x) -> bool

Returns True when the argument x is true, False otherwise. The builtins True and False are the only two instances of the class bool. The class bool is a subclass of the class int, and cannot be subclassed.

Value:
True
