The reason it is displaying None is because print() returns none, and you are sending that into input().

Either do:

print("Please enter distance in miles: ")
n = int(input())
# this will wait for input on the next line

or

n = int(input("Please enter distance in miles: "))
# this will wait for input on the same line as the text

The km_mi function doesn't seem to have any purpose and you can delete it and the other line further down referencing it. If this is for something like a school assignment that requires you to write a km_mi function, it's not clear from your code what the requirement is for this function.
