Is it possible to return a value from one Python file to another? [duplicate]

I'm wondering if it is possible to run another file: os.startfile('File.py') and have that file return a value to the file that called the other file.

For example, you have File1. Is it possible for File1 to call and run File2 and have File2 return a value to File1?

How do you return a value from a Python script?

The Python return statement is a special statement that you can use inside a function or method to send the function's result back to the caller. A return statement consists of the return keyword followed by an optional return value. The return value of a Python function can be any Python object.

Why are you running Python scripts like that? the usual way is to import one module ("another file") in a Python script and invoke the public functions from there. That's what the module importing mechanism is for, please read the linked documentation.
