Calling a JSON API using Python

Question

I was working on some online assignment, there I need to work on a program that will prompt for a location, contact a web service and recover JSON for the web service and parse that information, and retrieve the first place_id from the JSON. A place ID is an identifier(textual ) that uniquely distinguishes a place within Google Maps. API End Points

To finish this assignment, we should use this API endpoint that has a static subset of the Google Data.

I have worked on this assignment, but the codes are not operating. I am getting JSONDecodeError whenever I execute the program.

import urllib.request, urllib.parse, urllib.error

import json

adr= 'http://py4e-data.dr-chuck.net/json?'

while True:

    loca= input('Enter Location: ')

    if len(loca)<1:break

    url=adr + urllib.parse.urlencode({"address": loca})

    print('Retrieving', url)

    fha=urllib.request.urlopen(url)

    data=fha.read().decode()

    print('Retrieved', len(data))

    jsdata=json.loads(str(data))

    placeid= jsdata['results'][0]['place_id']

    print('The Place ID is: ', placeid)

Answer 1

It appears that the error is that this requires an extra parameter (Key)

Missing/incorrect key = parameter (it is an easy number to guess) ...

Edit: Check the documentation https://www.py4e.com/code3/geodata/README.txt

Example 1: http://py4e-data.dr-chuck.net/json?key=42&address=Monash+University

Example 2: http://py4e-data.dr-chuck.net/json?key=42&address=Kokshetau+Institute+of+Economics+and+Management
