How to add hour from input value

Can anybody help me to do this exercise:
I am a new learner for Python
In 24-hour time, hours run from 0 o’clock (midnight) to 23 o’clock (aka 11 pm). Write a program that asks the user for the current hour and for how many hours in the future they want to go. Have the program print out what the hour will be that many hours in the future. For instance, if it’s 13 o’clock now, 27 hours from now it will be 16 o’clock

Could you reply it in this forum. I believe others learner may want to know too.
Thanks a lot!
