handle_sample function

(Shortest import: from brian2.synapses.parse_synaptic_generator_syntax import handle_sample)

brian2.synapses.parse_synaptic_generator_syntax.handle_sample(*args, **kwds)

Checks the arguments/keywords for the sample iterator

Should have 1-3 positional arguments and 1 keyword argument (either p or size).

Returns a dict with keys low, high, step, sample_size, p, size. Default values are low=0, step=1`. Sample size will be either ``'random' or 'fixed'. In the first case, p will have a value and size will be None (and vice versa for the second case).
