That's right, you need some kind of loop, and a while-loop would be just fine. I see you've a way to exit your program (option 5), and because you have that, it's easy to wrap a loop around the rest of the code.
Code:
while True:
# Everything you want to have in the loop
# ...
The reason why I talked about your option 5, is because normally a while-loop will run while its condition is true, but because you've an alternative way of quitting, we can simply make the loop run forever (of course, until your alternative way will stop it)
