Boolean Error (test case 2)

Question

Can anyone see why I’m getting an error with the input 20 and 4 saying “Closed”?

with the following:

hour = int(input())
day = int(input())
if 10<= hour <21 and 1>= day <=5:
print("Open")
else:
print("Closed")

Answer 1

if 10<=hour<21 and 1<=day<=5:

not 1>=day<=5

Answer 2

Taking it step by step, Python evaluates the if condition as:

1. 10<=20<21 and 1>=4<=5

2. (10<=20 and 20<21) and (1>=4 and 4 <=5)

3. (True and True) and (False and True)

4. True and False

5. False

Since the if condition evaluated to False, the else block is executed. Hence, 'Closed' is printed.
