Hello Everybody...
Here is a code (tested)
class Test:
def __le__(self,other):
print " <= "
def __ge__(self,other):
print " >= "
def __add__(self,other):
print " + "
def __radd__(self,other):
print " r+ "
Suppose s is an instance of Test.
s=Test()
s>=100
prints >=
but 100>=s
prints <=
The point here is mathematically it is right but not modelling wise.
By modelling I mean, the user wants to preserve the order in which he
typed the
expression.
Is there a way to obtain the radd behavior in __ge__ and __le__ with
current syntax..
Regards
Balaji
