Question

Python : Write the function inAWhile that takes two integers t and d, where t is the present time on a 12-hour clock, rounded to an integer (so t is an integer in the interval [1,12]) and d is an integer increment in hours, and returns the time on a 12-hour clock in d hours. For example, in 2 hours from 3 o’clock, it will be 5 o’clock, so inAWhile (3, 2) = 5. Notice that 12 is followed by 1 on a 12-hour clock, since only computer scientists start counting at 0. The test data will clarify. Additionally, you should guarantee that the type of the parameters is int, using an assertion. For example, inAWhile (‘Hi’, ‘there’) should fail the assertion, and inAWhile (5, ‘there’) should also fail the assertion.

Answer 1

PYTHON CODE:

def inAWhile(t,d):

    # checking the parameters types and report error
    assert isinstance(t,int) and isinstance(d,int) ,"t and d must be integer"
  
    # finding the total of d and t
    total=t+d

    # checking for total greater than 12
    if total > 12:

        # checking for 12 when subtracting 12 from 12
        if total - 12 == 12:
            return 12
        else:

            # returning the time in 12 hours format
            return (total -12) % 12
    else:
        # return the sum of t and d when total is less than 12
        return t + d

# testing
if __name__=='__main__':

    print(inAWhile(10,5))
    print(inAWhile(3,2))
    print(inAWhile(1,1))
    print(inAWhile(12,11))
    print(inAWhile(8,8))
