difference between is and == in python

"is" vs "=="


-------------------------





"is" expressions evaluate to True if two variables point to the same object.


"==" evaluates to True if the objects referred to by the variables are equal.









>>> a = [1, 2, 3]


>>> b = a

>>> a is b


True


>>> a == b


True

>>> c = list(a)

>>> a == c


True


>>> a is c


False
