Question

Write a program in Python using loop that asks for the names of three runners and the time it took each of them to finish a race. The program should display who came in first, second, and third place. Think about how many test cases are needed to verify that your problem works correctly.

Answer 1

Python code:

#initializing a list name to store the name
name=[]
#initializing a list time to store the time of each runner
time=[]
#loop to accept the time and name
for i in range(3):
    #asking name of runner
    name.append(input("Enter name of runner "+str(i+1)+": "))
    #asking for time took
    time.append(int(input("Enter the time took to fininsh the race(in seconds): ")))
#checking if the 1st runner took the shortest time
if(time[0]<time[1] and time[0]<time[2]):
    #printing first is 1st runner
    print("first: "+name[0])
    #checking if the 2nd runner took the second shortest time
    if(time[1]<time[2]):
        #printing second is 2nd runner
        print("second: "+name[1])
        #printing third is 3rd runner
        print("third: "+name[2])
    else:
        #printing second is 3rd runner
        print("second: "+name[2])
        #printing third is 2nd runner
        print("third: "+name[1])
#checking if the 2nd runner took the shortest time
elif(time[1]<time[0] and time[1]<time[2]):
    #printing first is 2nd runner
    print("first: "+name[1])
    #checking if the 1st runner took the second shortest time
    if(time[0]<time[2]):
        #printing second is 1st runner
        print("second: "+name[0])
        #printing third is 3rd runner
        print("third: "+name[2])
    else:
        #printing second is 3rd runner
        print("second: "+name[2])
        #printing third is 1st runner
        print("third: "+name[0])
else:
    #printing first is 3rd runner
    print("first: "+name[2])
    #checking if the 1st runner took the second shortest time
    if(time[0]<time[1]):
        #printing second is 1st runner
        print("second: "+name[0])
        #printing third is 2nd runner
        print("third: "+name[1])
    else:
        #printing second is 2nd runner
        print("second: "+name[1])
        #printing third is 1st runner
        print("third: "+name[0])
