![]() Now the elif body will be executed if condition1 is False and condition2 is True. The if body will be executed if condition1 is True. This is the branching syntax: if condition1:Īn elif statement must follow an if statement, and the body will only be executed if the if statement condition is False. In Python, we branch our code using if, elif, and else. not a: True if a is False, False if a is True.a or b: True if either a or b or both are True.a and b: True if both a and b are True.They execute one thing when the condition is true and something else when the condition is false. The python if elif else statement is used to conditionally execute a statement or a block of statements. Wishbankaccount = $330 Cheat Sheet Python If Else Statementįriendly link to Cheat Sheet Page If Elif Else Cheat Sheet If mybankaccount wishbankaccount else print(f"wishbankaccount = ") mybankaccount = $2 Here indention is not needed, though this can get lengthy and hard for others to read your code. Make sure with the if else shorthand the body goes first then the if condition, then else condition with body. If you have only one statement to execute, you can put it on the same line as the if statement, or if you have only one if statement, and one else statement, you can put it all on the same line. Print("I am not broke!") I am not broke! Short Hand If and If Else The top two conditions are False so it prints "I am not broke!". Like if nothing else is True, do this instead. The else keyword is for anything that isn’t caught by the preceding conditions. Print("I broke even!") I broke even! Else Though mybankaccount is = equal to wishbankaccount so the condition is True and prints "I broke even!". So wishbankaccount is not > greater than mybankaccount which makes it False. The elif keyword is pythons way of saying, if the previous condition is not true, then try this condition. IndentationError: expected an indented block Elif Here I don’t indent the body of the if statement so Python doesn’t know it goes to the if statement above and gives an IndentationError. Python uses indentation (empty space at the beginning of a line) to define which body of code goes which line in the code. Print("I am BROKE!!!") I am BROKE!!! Indentation In this example, my wishbankaccount is greater > than mybankaccount so it prints "I am BROKE!" mybankaccount = 0 These conditions can be used in several ways, most commonly in if statements and loops. ![]() Python uses the logic conditions from mathematics: If the comparison evaluates to False, then the code block is skipped and will move on to the next line of code. If the comparison is True, the code in the body is executed. The body of the if statement is then indented to the right. We start with the if keyword, followed by our comparison, then with a colon. So, an if statement is used to evaluate a comparison using conditionals. If you knew that, you wouldn’t be reading this. ![]()
