# What happens if I edit my Python files while a sweep is running?

The behavior depends on which file you edit. While a sweep is running:

* If the `train.py` script that the sweep uses changes, the sweep continues to use the original `train.py`.
* If files that the `train.py` script references change, such as helper functions in the `helper.py` script, the sweep uses the updated `helper.py`.
