Could a variable be imported from one file, processed, and then have the result returned to the original file?

edit

Yes, it is possible to import a variable from one file, process it in another file, and then return the result to the original file. This can be done through functions and modules in programming languages such as Python, Java, and JavaScript. The variable can be passed as a parameter to the processing function in the second file, and the processed result can be returned and assigned to the original variable in the first file.
