On WIndows 10, running Python programs in a DOS box, I would like one
Python program to chain to another. I.e. the first program to be

unable to so this. I am using Python 3.8.3. Some attempts so far (may
be nonsensical):
What is the definition of "finish" in the first program?
Not sure if have understood <<<(*not* waiting for the second to finish,

In Python, the easiest way to chain two "modules" is to use import. This
gives full control to the 'import-er'.
With exec, the intention is to *replace* the current program, not to
invoke it and wait till it's done. The current program will not
continue after a successful exec.
As a 'general rule', isn't exec() something to be avoided?
With an appropriate conditional control between the three modules, and
bearing @Eryk's observations in-mind (and the lack of specifics in the
OP), won't the import option succeed and won't all of file1's attributes
be garbage-collected? Same effect, or something missing?
