Object Comparison

== two object values are equal

>>> x=[1,2]

>>> x==y   
True       
>>> x is y
False      

Reference Comparison

is operator can be used to find whether two variables point same reference or not

>>> x=[1,2]
>>> y=[1,2]
>>> z=x
>>> x is y
False
>>> x is z
True

Notice: x and z are pointing to same Reference
