In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a.As a is 33, and b is 200, we know that 200 is greater than 33, and so we print to screen that "b is greater than a".. Indentation. Python supports the usual logical conditions from mathematics: Equals: a == b Not Equals: a != b Less than: a < b Less than or equal to: a <= b Greater than: a > b Greater than or equal to: a >= b These conditions can be used in several ways, most commonly in "if statements" and loops.
