In this case, Python thinks our if statement is empty, which results in an error. An if statement can have an optional else clause. The else statement executes if the condition in the if statement evaluates to False. ... True - the body of if executes, and the body of else is skipped.

December 2, 2022 - It can be helpful to think of conditional statements as a set of rules for Python to follow. ... In a loop, you can use the jump statement break. break enables you to move the flow of program execution outside the loop once a specific condition is met. In a function, you can use return or yield to exit an if statement. Elif is the shortened version of else if. It enables you to perform a series of checks to evaluate the conditions of multiple expressions. For example, suppose the first statement is false, but you want to check for another condition before executing the else block.

Python uses whitespaces to indicate which lines are controlled by the if statement. The if statement controls all indented lines below it. Typically, the indentation is set to four spaces (read this post if you’re having trouble with the indentation). As a simple example, the code below prints a message if and only if the current weather is sunny:

12345 steps_taken = 7500 step_goal = 10000 if steps_taken < step_goal: print(f"Keep going! You need {step_goal - steps_taken} more steps to reach your goal.") ... The condition steps_taken < step_goal checks if the number of steps taken is less ...
