How to Use Python Not Equal in an If Statement Understanding these differences can ensure that your code runs as smoothly as possible. != evaluates whether two items are not equal to the same value.is not evaluates whether two expressions point to the same place in memory.However, there are some nuanced differences. ![]() In this example, it may seem that these perform the same function. Let’s take a look at an example: # Comparing != and not in Python There are some key differences here, however. It may seem that we can use the not equal operator in Python interchangeably with the not keyword. One of the great things about Python is the ability to use plain-English words to write your code. Python Not Equal Operator Versus Not Keyword != is available in both Python 2 and Python 3īecause the operator has been deprecated in Python 3, to future proof your code (if you’re still running Python 2), it’s better to use !=.Python 2 had two not equal operators available: The equality operator checks for equality and will return a True if the values are equal to one another. The expression represents the inverse of the equality operator, =. Because that’s not the case, the expression returns True. ![]() We can see that when we evaluate whether or not 1 is equal to 2. Let’s take a look at an example: # A Basic Example of the Not Equal Operator Return False if the two expressions are equal.Return True if the two expressions are not equal.The Python not equal operator is written as != and returns a boolean value evaluating if the expressions are not equal.

Shift right by pushing copies of the leftmost bit in from the left, and let Python divides the operators in the following groups:Īrithmetic operators are used with numeric values to perform common mathematical operations: OperatorĪssignment operators are used to assign values to variables: OperatorĬomparison operators are used to compare two values: Operator Python Examples Python Examples Python Compiler Python Exercises Python Quiz Python Server Python Bootcamp Python Certificate Python How To Remove List Duplicates Reverse a String Add Two Numbers Module Reference Random Module Requests Module Statistics Module Math Module cMath Module Python Reference Python Overview Python Built-in Functions Python String Methods Python List Methods Python Dictionary Methods Python Tuple Methods Python Set Methods Python File Methods Python Keywords Python Exceptions Python Glossary Python MongoDB MongoDB Get Started MongoDB Create Database MongoDB Create Collection MongoDB Insert MongoDB Find MongoDB Query MongoDB Sort MongoDB Delete MongoDB Drop Collection MongoDB Update MongoDB Limit Python MySQL MySQL Get Started MySQL Create Database MySQL Create Table MySQL Insert MySQL Select MySQL Where MySQL Order By MySQL Delete MySQL Drop Table MySQL Update MySQL Limit MySQL Join Machine Learning Getting Started Mean Median Mode Standard Deviation Percentile Data Distribution Normal Data Distribution Scatter Plot Linear Regression Polynomial Regression Multiple Regression Scale Train/Test Decision Tree Confusion Matrix Hierarchical Clustering Logistic Regression Grid Search Categorical Data K-means Bootstrap Aggregation Cross Validation AUC - ROC Curve K-nearest neighbors Python Matplotlib Matplotlib Intro Matplotlib Get Started Matplotlib Pyplot Matplotlib Plotting Matplotlib Markers Matplotlib Line Matplotlib Labels Matplotlib Grid Matplotlib Subplot Matplotlib Scatter Matplotlib Bars Matplotlib Histograms Matplotlib Pie Charts ![]() Python Modules NumPy Tutorial Pandas Tutorial SciPy Tutorial Django Tutorial Python Dictionaries Access Items Change Items Add Items Remove Items Loop Dictionaries Copy Dictionaries Nested Dictionaries Dictionary Methods Dictionary Exercise Python If.Else Python While Loops Python For Loops Python Functions Python Lambda Python Arrays Python Classes/Objects Python Inheritance Python Iterators Python Polymorphism Python Scope Python Modules Python Dates Python Math Python JSON Python RegEx Python PIP Python Try.Except Python User Input Python String Formattingįile Handling Python File Handling Python Read Files Python Write/Create Files Python Delete Files
