In most cases in Python, you would almost never need to reference the
list's index directly since python makes it easy to use iterators;
however in your particular case, which is a valid exception, enumerate()
takes an optional second argument `start` which defines the number that
enumerate start to count with, i.e. you can do:

for i, option in enumerate(mainmenuoptions, 1):
    print('%s. %s' % (i, option))
