This block of code is called the "body" of the loop and it has to be indented. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. The third line checks if the input is odd. The most well-known example of this is the print statement, which went from a keyword in Python 2 to a built-in function in Python 3: This is one of the examples where the error message provided with the SyntaxError shines!
