Verbally, we can imagine we are telling the computer: "Hey if this case happens, perform some action" 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.
