+# Learning from this script and continuing development
+
+Rather than having to type out all 40 plus lines of data processing, you can also run the whole script in the interactive shell and play with it:
+
+After typing `python3` to get the interactive Python shell in this directory, you can do this line:
+
+```python
+exec(open('pomodoro_to_harvest.py').read())
+```
+
+And now you can interact with the resulting timelog DataFrame:
+
+```python
+timelog.query("time>30").loc[:100,["description","time","orig_desc"]].tail(50)
+```
