I have this class:
class Vector(object):
TOL = 1e-5
def __eq__( self, other, tolerance=TOL ):
print tolerance
shortened for clarity obviously. so I want to subclass this class like
so:
class BigVector(Vector)
TOL = 100
for example if I was working with large vectors which I knew would never
be very close hence the large tolerance. this doesn't work however -
the TOL class variable, while overridden in BigVector, is still using
the Vector.TOL variable in the __eq__ method.
which kinda makes sense to a certain degree, but how do I get the
behaviour where doing:
BigVector().__eq__( otherVec )
prints 100 instead of 1e-5?
does this question make sense? not sure how clearly I'm phrasing my
question... any of you guys python experts?
I *could* do this, but its ugly:
class Vector(object):
TOL = 1e-5
def __eq__( self, other, tolerance=None ):
if tolerance is None: tolerance = self.TOL
print tolerance
