Python Comparison Operators

Python Comparison Operators Askpython The comparison operators <> and != are alternate spellings of the same operator. != is the preferred spelling; <> is obsolescent. (reference: python language reference). As the documentation says: the operators <, >, ==, >=, <=, and != compare the values of two objects. is: check for identity the semantics are that the object (as held in memory) is the object. again, the documentation says: the operators is and is not test for object identity: x is y is true if and only if x and y are the same object.

I'm wondering how python does string comparison, more specifically how it determines the outcome when a less than < or greater than > operator is used. for instance if i put print ('abc' <. In python 2, always remember to override the ne function as well, as the documentation states: there are no implied relationships among the comparison operators. Python checks whether the object you're referring to has the same memory address as the global none object a very, very fast comparison of two numbers. by comparing equality, python has to look up whether your object has an eq method. if it does not, it examines each superclass looking for an eq method. if it finds one, python calls it.

In logic point of view it is enough to define two any operators (excluding pairs: == and !=, < and >=, > and <=). what is the minimum set of these operators to override in python?.

Since the determinative class for comparisons is the lh class, the class on the left needs to have the correct comparison operators to deal with the comparison with the class on the right. I've downvoted every answer because none of them gives a convincing reason, nor does pep8. it says "comparisons to singletons like none should always be done with is or is not, never the equality operators." are true and false "singletons like none"? apparently, so i guess i should say "if x is true"? are ints between 5 and 256 "singletons like none"? apparently (see @doublefelix 's answer.
