Thank you so much for the help.
I'm self-studying and watching tutorials on youTube. The problem was given
as an exercise after the tutorial.
I did modify my code based on the suggestions here and it helps.
Thank you!

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

Look at the tee command. If you control the subprocess, and it's written
in Python,
like this?
class Writers (object):

Because the former specifies the actual units and the latter does n

I should have stated that more clearly. You can enter the value in
degrees, but it will automati

Yeah, how about we read your mind or make wild guesses about why it's
not acceptable, and about what your requirements really are.

I thought I might be able to overload __rmod__, but apparently python
applies the % operator before __rmod__ is even invoked if the left-hand

Smiley noted, but consider:
c = complex()
=> what is the value of c here?
c.abs = 2**0.5
=> wha

As Fredrik indicated, you need to flush the output buffer. You might also
want to check out the prog
