First of all, it looks like your indentation is slightly off because
"def main" line is that the left margin and the other 2 "def" lines and
the "main()" line aren't.

You're not passing anything into 'get_input', neither are you saving
any result that it might be returning.

You're not passing anything into 'convert_kilo'.

You're defining 'get_input' to accept 1 parameter 'kilo'. Why? You're
assigning to 'kilo' in the first line, so any value you _did_ pass in
would be ignored.

You're defining 'convert_kilo' to accept 2 parameters. You're using the
'kilo' parameter, but not the 'miles' parameter because you're
assigning to it on the first line, so any value you _did_ pass in would
be ignored.

>   def convert_kilo(kilo,miles):

'kilo' is already a float, and you're multiplying it by a float, so the
'float' call is pointless.
