Hello Dynamic Paths

README.md

1. make setup
2. make test
3. cd hello; chalice local
4. curl http://localhost:8000/hello/world

I have left the static path in the app.py so it can be uncommented and the tests re-run to show it working / failing.

app.py

from chalice import Chalice

app = Chalice(app_name='hello')


@app.route('/{hello}')
def index(hello):
   return {'hello': hello}


# @app.route('/world')
# def index():
#     return {'hello': 'world'}
