Logical operators
In some cases, we would like to check for several conditions at the same time. Imagine we would like to print
Great weather in case the temperature is between 20 and 27, as well as there are no clouds. That could be done with an and statement:if 20 <= temperature <= 27 and clouds == 0:
print('Great weather')Python has 3 logical operators:
Logical operator | Example | Description |
and | if a and b: | If both a and b hold |
or | if a or b: | If either a or b hold |
not | if not a: | If a does not hold |
In python, they are evaluated with a priority of
not first, then and, and then or. So, if the expression has several not, and, and ors, the program would evaluate not operations first, then and operations, and only then will evaluate ors. It’s possible to force other priorities with parentheses.Challenge
Given 3 numbers, your task is to find out if any of those is even.
The input contains 3 integers. The program should print
Yes if any of the 3 numbers are even and No otherwise.Input | Output |
