!= Python Meaning and Uses

The Not Equal is a comparison operator in Python used to determine if two numbers are not equal. When the values being contrasted are not the same, the return value is true. The return value will be false if the numbers being compared are genuinely equal.

The Python Not Equal operator is represented by the symbol “!=”. There should be no divider between the exclamatory symbol and the equal symbol. “!” is the abbreviation for not.

The Not Equal Operator is commonly used in conditional statements like as If, If-Else, Elif, While, and so on.


The syntax for the Python Not Equal comparison operator is as follows.

Python Not Equal comparison operator

Operands 1 and 2 are datatype values.

The boolean result returned by the Not Equal operator is true or false. If operands 1 and 2 are not equal, the operator returns True; otherwise, it returns False.

The not equal operator can be used in an if-else statement to check if user input is accurate. For example, if a teacher wished to double-check their pupils’ responses to the question “What is 24 x 2?” To ensure that the pupils’ answers matched the answer key, the instructor may use the following code:

Python Not Equal Operator

The application displays “Incorrect response” if the solution is not equal to 48. If the solution is 48, the program proceeds to the else section, where it outputs “Correct.”

Previously, the symbol <> signified “not equal to” in Python.

Example of Python’s !=

Our first case in point will demonstrate how to use the NOT EQUAL operator to compare two or even more variable type values. Now that the tool is open, don’t forget to enable Python support. In the script, two integer-type variables, “x” and “y,” have been initialized. Following that, we used the != sign to compare both variables’ values, and the Boolean output was saved into a new variable called “c.” The Boolean result that has been put in the variable “c” will be displayed at the end of the code.

Python Not Equal Operator example

Because both values in the data type were equal and the same, the outcome will be “False.”

The code has been updated as follows. We defined three variables, two of which had the same value and the third of which had a different value. In the first sentence, we used the NOT Equal operator to report the outcome of the value compared between variables a and b. Then, outside of the print statement, we compared variables “a” and “c” and displayed the result. Then, in the print statement, we declared a string type variable “q” and compared it to the integer variable “a.”

When comparing separate variables, you will see that the output has one False and two True values. The first two comparisons were between integer and string type variables, while the third was between integer and string type variables. As a result, it returns True since the two aren’t equal.

Using Python’s != with If Statements

Let’s have a look at how the Not Equal operator is utilized in the python “if” statement. In the code, we utilized two variables. The integer type of variable “a” is used, but the string type of variable “b” is used. Then we’ve set up the “if” statement and utilized the NOT EQUAL operator on both operands to see if they’re equal. Print a statement at the ending.

Using Python’s != with If Statements

The result of the preceding code will clearly state “a is not equal to b,” which is correct since that’s the case.

Using Python’s != with If-Else Statements

The “if” statement was used in the preceding example. In this example, we will utilize the “if-else” expression. The code has been updated as follows. To begin, set the value of an integer type variable “a” to 7. After that, in our code, we utilized the if-else expression. The “is not” operator is used in the “if” component of the statement to compare the variable “a” with a value of 19. If the condition is true, our “Values are not Equal” will be printed; otherwise, control will be handed to the “else” expression, which will print “Values are Equal.”

Python’s != with If-Else Statements

The output for the code above will display “Values are not equal”, since the first declared value is not equal to the second.

Using Python’s != with Complex Functions

Finally, we’ll test the NOT EQUAL comparison operator with a more sophisticated example this time. As a result, we’ve created a class called “Demo”.  We’ve set the value of a variable called “i” to 0 in this class. The value “none” has been assigned to another variable, “data”.  Following that, we created a constructor for this class to retrieve the values of those same variables from the class instance. Then we utilized the “if-else” expression to initialize an embedded NOT EQUAL function in our code. To send values to the constructor, three objects have been constructed. Following that, we used the print statement to compare the objects and print out the results of the comparison.

Since the values assigned to both objects were the same, the result show False as a response to the first print command. The second print statement, on the other hand, returns True since t2 and t3 have distinct values which are not equal.
