Change the above call to:
kilos = get_input()
This is because your function returns that value

This one you need to pass the kilos argument, and you don't need to pass
the miles parameter (see below)
convert_kilo(kilos)

You defined get_input with no parameters, so it gets no arguments when you
call it:
def get_input():

Make the above:
def convert_kilo(kilo):

When you define a function, the names between the parentheses are called
parameters. When you call the function, they are called arguments. They
need to match. When you return a value from a function, you need to put a
name to it, or it is lost.
