Syntax of if-else Statement

The if-else statement is one of the most commonly used constructs in Python, allowing the program to make decisions based on conditions.

The basic syntax of the if statement is as follows:

The if statement checks if a condition is true. If it is, the code inside the block will be executed.

In the case of the else statement, you don't need to explicitly define the condition, as it automatically covers all scenarios where the if condition is false:

This diagram illustrates the flow of an if-else statement. It shows that if a condition is true, the program executes the if code block. If the condition is false, the else code block is executed. The process concludes after one of the blocks is executed.

Example: Checking if a User Met Their Step Goal

1234567
steps_taken = 9000 step_goal = 10000 if steps_taken >= step_goal: print("Great job, you've reached your step goal!") else: print("Keep going, you're almost there!")
copy

In this example, the program checks if the number of steps taken by the user is greater than or equal to the step goal. If the condition is met (i.e., the user has reached or exceeded their step goal), the program prints a congratulatory message. If the condition is not met, the else block will execute, encouraging the user to keep going.
