This is different compared to other programming languages. >>> help("keywords") Here is a list of the Python keywords. Here, we shall be creating a user-defined function name calc () which accepts one argument. Decisions in a program are used when the program has conditional choices to execute a code block. Python Loops Python Date and Time . is used to combine conditional statements: Test if a is greater than To handle the situation Python allows adding any number of elif clause after an if and before an else clause. Within the if - else if expression2 evaluates true then statement_3, statement_4 will execute otherwise statement_5, statement_6 will execute. It allows us to check for multiple expressions. Let's confirm we wrote the code correctly. They aren't hard to learn and can gracefully handle situations that aren't as amenable to dictionary lookup logic: 'A' if grade>=90 else 'B' if grade>=80 else 'C' if grade>=70 else 'F' . ago.
