In the following Python Programming Language, the output is 3 because the variable x is equal to 21, then the user check the condition is the variable x is greater than 21 then print it print 1, otherwise the user check that the variable x is less than 21 then print 2, otherwise it print 3. So, the variable x is not greater than 21 or not less than 21, it is equal to 21. That's why the code execute the else block and print 3.
