How Do I Use Python to Make HTTP Requests and Parse JSON Data from the Google Directions API?

HTTP Requests and JSON Parsing in Python

In Python, there are powerful libraries that simplify sending HTTP requests and parsing JSON responses. One such library is the popular "requests" library.

To query the Google Directions API and obtain route calculations, you can follow these steps using the "requests" library:

Step 1: Import the Library

import requests

Step 2: Define the Request Parameters
Construct a dictionary with the necessary parameters, including the origin, destination, waypoints, and the 'sensor' parameter set to 'false'.

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)

Step 3: Send the Request
Send a GET request to the Google Directions API URL along with the parameters.

resp = requests.get(url=url, params=params)

Step 4: Parse the JSON Response
The API returns a JSON response. Use the json() method on resp to parse the response.

data = resp.json()

Additional Information:

• Refer to the "JSON Response Content" documentation provided in the response for further details on accessing the JSON data.
• The "requests" library offers various options for configuring requests and handling responses. Explore its comprehensive documentation for more advanced usage.
