Question

what will be the output of this program?
number = 5
greater_than_zero = number > 0
less_than_zero = number < 0

if greater_than_zero:
print(number)
if less_than_zero:
print(number + 1)
if greater_than_zero and less_than_zero:
print(number + 2)
if greater_than_zero or less_than_zero:
print(number + 3)

Explanation:

Step1: Evaluate boolean variables

number = 5. greater_than_zero = 5 > 0 → True. less_than_zero = 5 < 0 → False.

Step2: Execute first if - statement

Since greater_than_zero is True, print(number) → 5.

Step3: Execute second if - statement

Since less_than_zero is False, the code inside this if - block (print(number + 1)) is not executed.

Step4: Execute third if - statement

Since greater_than_zero and less_than_zero is True and False → False, the code inside this if - block (print(number + 2)) is not executed.

Step5: Execute fourth if - statement

Since greater_than_zero or less_than_zero is True or False → True, print(number + 3) → 5+3 = 8.

Answer:

5
8
