OK, it will go something like this

open input.txt and output.txt files
read input from user (or whereverit comes from)
write input to input.txt
process input data
write result to output.txt
close input.txt and output.txt

Now which parts of that are you struggling with?
Do you not know how to do any of the steps?

The normal way to do that is to perform an integer division by 2
and check the remainder part to see if it is zero. If the remainder
is zero then the number must be even.

Python has a couple of tools to help with that. The first is the
divmod() function and the second is the modulo operator (%) which
returns the remainder part only.

If you need more help please get back to us.
