Extract_data_from_API

# Access-Web-Data-with-Python
# In this program, I use Python code to prompt for a location, contact a web service 
# and retrieve JSON for the web service and parse that data, 
# and retrieve the first place_id from the JSON. 
# A place ID is a textual identifier that uniquely identifies a place as within Google Maps.
The project came from *Using Python to Access Web Data* on Coursera.
