How are you actually running your code?
"None" is the default return value of all functions in Python. But, the
interpreter is supposed to suppress it as a displayed result.
As a side note, both your km_mi() function and the line "answer = km_mi"
are certainly wrong, but it is not clear what you intend to do.
