# Trees To change the output of the tree, read the data.py file. Install one (optional) package: `bs4` (Beautiful Soup 4), with `pip install -r requirements.txt`. This will make the output "pretty" (i.e. indented). To print the output to terminal, run `python tree.py` To save to a file, run `python tree.py file.html`. To append to an already existing file, run `python tree.py >> file.html`
