Write a Python program 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.

Calling a JSON API.py
# To complete this assignment, you should use this API endpoint that has a static subset of the Google Data:
# http://py4e-data.dr-chuck.net/json?
# This API uses the same parameter (address) as the Google API. This API also has no rate limit so you can test as often as you like.
# If you visit the URL with no parameters, you get "No address..." response.
# To call the API, you need to include a key= parameter and provide the address that you are requesting as the address= parameter that
# is properly URL encoded using the urllib.parse.urlencode() function as shown in http://www.py4e.com/code3/geojson.py
# Make sure to check that your code is using the API endpoint is as shown above.
# Please run your program to find the place_id for this location: University of Akron
# Make sure to enter the name and case exactly as above and enter the place_id and your Python code below. Hint: The first seven characters of the place_id are "ChIJbye ..."

Please help me out: I checked my code and the code above. It all turns out that the Plus code for the location 'Indiana University at Bloomington' is 86MPV5HX+JM. It doesn't starts with 8554M as required in the Hint part. So I could not submit my assignment.
Calling a JSON API

In this assignment you will write a Python program somewhat similar to http://www.py4e.com/code3/opengeo.py. The program will prompt for a location, contact a web service and retrieve JSON for the web service and parse that data, and retrieve the first plus_code from the JSON. An Open Location Code is a textual identifier that is another form of address based on the location of the address.
To complete this assignment, you should use this API endpoint that has a static subset of the Open Street Map Data.
http://py4e-data.dr-chuck.net/opengeo?
Please run your program to find the plus_code for this location: Indiana University at Bloomington
Make sure to enter the name and case exactly as above and enter the plus_code and your Python code below. Hint: The first five characters of the plus_code are "8554M ..."

Test Data / Sample Execution

You can test to see if your program is working with a location of "South Federal University" which will have a plus_code of "6FV8QPRJ+VQ".

$ python solution.py

Make sure to retreive the data from the URL specified above and not the normal Google API. Your program should work with the Google API - but the plus_code may not match for this assignment.
