The "not equal to" operator is a comparison operator, and it returns a boolean value ( True or False) based on the comparison. The operator returns
if both the operands are of different data types or values, else it returns False. Python is a dynamic and strong typed language which mean it compares the variable data type as well its value when it comes to "equal to" and "not equal to" operators.
Python not equal operator With Example
In python 3 we represent the "not equal to" operator by
>>> 20 != 30 True >>> 20 != "20" True >>> 20 != 20 False
The != operator only operate between two operands or variables.
Python "not equal to" custom object
When we use the "not equal to" operator between two variables or objects, then at the backend the
method operates. This means we can use this Dunder method to create such user objects which could use python "not equal to"
class Student: def __init__(self, name, lan): self.name= name self.lan = lan # Return True if two Student objects has different languages # If both student has same languages return False def __ne__(self,other): if self. lan != other.lan: return True else: return False rohit = Student("rohit", "Python") himanshu = Student("himanshu", "Java") raj = Student("raj", "Python") print("rohit != himanshu", rohit !=himanshu) print("rohit != raj", rohit!=raj)
rohit != himanshu True rohit != raj False
In python, the not equal operator is represented by
- The operator can operate between two objects or variables.
- It returns True if both the variable has different values or data types.
- It returns False if both the variables have similar values and data type.
- For user-defined functions, it can be customise using __ne__() dunder.
