Please help!!!

I need to write a really simple python program to solve this issue. I have most of the program written but, when I run the second example, the result is incorrect. Examples 1 and 3 work just fine.

Write a program to calculate the number of seconds since midnight. For example, suppose the time is 1:02:05 AM. Since there are 3600 seconds per hour and 60 seconds per minutes, it has been 3725 seconds since midnight (3600 * 1 + 2 * 60 + 5 = 3725). The program asks the user to enter 4 pieces of information: hour, minute, second, and AM/PM. The program will calculate and display the number of seconds since midnight. [Hint: be very careful when the hour is 12].

Examples for testing code:

Enter hour: 1 Enter minute: 2 Enter second: 5 Enter AM or PM: AM Seconds since midnight: 3725

Enter hour: 11 Enter minute: 58 Enter second: 59 Enter AM or PM: PM Seconds since midnight: 86339

Enter hour: 12 Enter minute: 7 Enter second: 20 Enter AM or PM: AM Seconds since midnight: 440

Here is the code that I have written: As I have said, It should be a simple program.

Thank you in advance for your help!!!!

hour = float(input("Enter hour:")) minute = float(input("Enter minute:")) second = float(input("Enter second:")) am_pm = input ("Enter AM or PM:") if am_pm == "am" and hour == 12: hour = 0 seconds_since_midnight = ((3600 * hour) +(minute *60) + second) print("Seconds since midnight:", seconds_since_midnight)
