« The order in which program statements are executed is called the flow of control.
« The if…else… statement lets your program choose between two options.
« The nested if structure allows you to place one if statement inside another.
« The ternary operator allows you to perform conditional checks and assign values or execute expressions
in a single line.
« The for loop repeats a block of statements a fixed number of times.
« A while loop repeats a set of instructions as long as a given condition is true.
« Python offers two jump statements—break and continue, which are used within loops.
