PhaseSpace

class remu.binning.PhaseSpace(variables)

A PhaseSpace defines the possible combinations of variables that characterize an event.

Parameters:

variables : iterable of strings

The set of variables that define the phase space.

Notes

A PhaseSpace can be seen as the carthesian product of its variables:

>>> ps = PhaseSpace(variables=['a', 'b', 'c'])
>>> print ps
('a' X 'c' X 'b')

You can check whether a variable is part of a phase space:

>>> 'a' in ps
True

Phase spaces can be compared to one another.

Check whether two phase spaces are identical:

>>> PhaseSpace(['a','b']) == PhaseSpace(['b', 'a'])
True
>>> PhaseSpace(['a', 'b']) == PhaseSpace(['a', 'c'])
False
>>> PhaseSpace(['a', 'b']) != PhaseSpace(['a', 'c'])
True

Check whether one phase space is a sub-space of the other:

>>> PhaseSpace(['a', 'b','c')] > PhaseSpace(['a', 'b'])
True
>>> PhaseSpace(['a', 'c']) < PhaseSpace(['a', 'b','c'])
True
