In computer programming, we use the if statement to run a block of code only when a specific condition is met. In this tutorial, we will learn about Python if...else statements with the help of examples.
Learn how If-Else Statements control code flow, create dynamic programs, and unlock Python's full potential. Dive into clear examples and expert guide.
Python If Else. Python Glossary. Else. The else keyword catches anything which isn't caught by the preceding conditions. Example Get your own Python Server. a = 200. b = 33. if b > a: print("b is greater than a") elif a == b: print("a and b are equal") else: print("a is greater than b") Try it Yourself »
There is also syntax for branching execution based on several alternatives. For this, use one or more elif (short for else if) clauses. Python evaluates each <expr> in turn and executes the suite corresponding to the first that is true. If none of the expressions are true, and an else clause is specified, then its suite is executed:
How to Use the else Statement in Python. The else statement allows you to execute a different block of code if the if condition is False. Here's the basic syntax: if condition: # code to execute if condition is true else: # code to execute if condition is false
With Python’s if/else statement we evaluate a Boolean true/false condition. When True, code in the if block executes. When the condition tests False, the else code runs. That way always one of two paths run. In plain English, an if/else statement reads as: “if this condition is true, execute the following code. Else run the other code”.
How do Python if..else statements work? An if statement runs code only when a condition is met. Nothing happens otherwise. What if we also want code to run when the condition is not met? That's where the else part comes in. The syntax of an if..else statement looks like this:
Python if…else statement Typically, you want to perform an action when a condition is True and another action when the condition is False . To do so, you use the if...else statement.
Python's if statements make decisions by evaluating a condition. When True, code indented under if runs. Else our program continues with other code.
elif is short for else if. Unlike else with elif you can add an expression. That way instead of writing if over and over again, you can evaluate all cases quickly.
