Case switch python

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. An "if statement" is written by using the if …
