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.

Mar 7, 2025 · Below is the flowchart by which we can understand how to use if-else statement in Python: In this example, the code assigns the value 3 to variable x and uses an if..else statement to check if x is equal to 4. If true, it prints “Yes”; otherwise, it prints “No,” demonstrating a conditional branching structure.

Mar 8, 2025 · If…Else statement allows to execution of specific blocks of code depending on the condition is True or False. if statement is the most simple decision-making statement. If the condition evaluates to True, the block of code inside the if …

Python supports the usual logical conditions from mathematics: These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using the if keyword. In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a.

Mar 3, 2022 · In Python, if statements are a starting point to implement a condition. Let’s look at the simplest example: When <condition> is evaluated by Python, it’ll become either True or False (Booleans).

Think of them as the decision-makers in your code. Python offers three main types of conditional statements: if statement; if-else statement; if-elif-else statement; The Simple if Statement. The if statement is the most basic form of conditional execution in Python. It runs a block of code only if a specified condition evaluates to True. Here ...

Aug 28, 2024 · Conditional statements, commonly referred to as "if-then" statements, allow your code to perform different actions based on a condition that evaluates to either True or False. Conceptually, you can think of them as "decision points" …

Mar 7, 2023 · In this article, we'll explore how to use if, else, and elif statements in Python, along with some examples of how to use them in practice. The if statement allows you to execute a block of code if a certain condition is true. Here's the basic syntax: The condition can be any expression that evaluates to a Boolean value (True or False).

For these purposes, Python provides the following constructs: 1. If statements. 2. If-else statements. 3. Elif ladders. 4. Nested if-else statements. We will discuss each of them with examples in the following sections of this article. If statements take an expression, which is the condition it checks.

You use the if statement to execute a block of code based on a specified condition. The syntax of the if statement is as follows: if -block Code language: Python (python) The if statement checks the condition first. If the condition evaluates to True, it executes the statements in the if-block. Otherwise, it ignores the statements.
