using subpocess for both reading and writing simultaneously

[woooee]

Put the code in a function. The second program imports cpt and runs a function that inputs the value and returns it to the calling program. Obviously you can do this a 2nd time for the 2nd input.

It does not import - it tries to run another program as an external process (and does not do it right in the process - pun intended ).
