Python is dynamically, but strongly typed , and other statically typed languages would complain about comparing different types . So if the two variables have the same values but they are of different type, then not equal operator will return True.

str = 'halo' if str == 'halo': # equal print ("halo") elif str != 'halo': # not equal print ("no halo")

Python is not

The is operator is the object identity operator used to check if two objects in fact are the same and its negation is not : x is y is true if and only if x and y are the same object.

x = 2 if x is not 3: print("not equal") else: print("equal")

The above example will print "not equal" as x = 2 as assigned earlier.

Python Comparison Operators

A comparison operator , also called python relational operator, compares the values on both sides of the operator to classify the relation between them as either true or false .
