Python not equal operator

In this post, we will see about Python not equal operator.

Not equal operator is denoted by != in Python and returns true when two variables are of same type but have different value. If two variable posses same value, then not equal operator will return False.


Python not equal operator example

Here is simple example of non equal operator

This will print True.

Output:

False
True

str1!=str2 returns False:
As str1 and str2 are exactly same String, so it return False.

str1!=str3 returns True:
As str1 and str3 differ in case, it return True.

Please note that you can use <> for not equal in Python 2 but <> is deprecated in Python 3.


Python not equal operator in case of Custom object

When you call !=, python internally calls ne(self, other) method. In case of custom objects, you can implement your own version in the class.

Here is quick example.

Output:

False
True

As you can see, we have implemented ne(self, other) and two countries are not equal, if there name are not same.

So that’s why
india1 != india2 returned False as name is same in both objects even though population is different.

That’s all about Python not equal operator.
