Return data from python script to another python scrip

I would like to call a python script from a different python script and pass the data back to the original on a windows machine.

Main python Script:
import OtherPythonScript

results = Execute OtherPythonScript

do x:
    record results to y

return y

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Put the functionality to a function inside the OtherPythonScript
def my_function():
    # get the y value somehow
    return y

Open in new window

and call the function from the other script -- almost as you guessed
import OtherPythonScript
result = OtherPythonScript.my_function()

Open in new window

I think @pepr solution will work if you can change your script into a function, but I think this may not be your final solution depending on your requirements.

Maybe a little more context on your problem could help us to direct you better.
A little context would help to give the right advice for your case.

My first impression is, that for most cases pepr gave exactly the right answer. (especially if the script that you want to call is under your control). Just import and call the function

Some options you have are:
1) import the python script as module and execute the functions required (pepr's suggestion if you can modify the code)
2) Same as above but start in a separate thread
3.) import the other module and use the multiprocessing module for data exchange
3.) start script as a subprocess, collect it's stdout
4.) start the other script / process, write the results to a file and read the file when the script is finished
5.) start the other script as an RPC server (XMLRPC), and perform RPC calls
