I have a Python program I'm building that can be run in either of 2 ways: the first is to call `python main.py` which prompts the user for input in a friendly manner and then runs the user input through the program. The other way is to call `python batch.py *-file-*` which will pass over all the friendly input gathering and run an entire file's worth of input through the program in a single go.

The problem is that when I run `batch.py`, it imports some variables/methods/etc from `main.py`, and when it runs this code:

```
import main

```

at the first line of the program, it immediately errors because it tries to run the code in `main.py`.

How can I stop Python from running the code contained in the `main` module which I'm importing?
