We will use the requests library to make an HTTP request from that URL and save the response objects text under the variable response: This shows what the response is to our HTTP request from the API. } There is a ton of data out there on the web and much of it exists in a specific format called JavaScript Object Notation (JSON). finally, you have a query question mark ?, followed by parameters, and the main parameter is your access_key. Of course, you can fine-tune this code to handle some issues like of the user entered the currency in a lowercase instead of the uppercase, or if the user entered a wrong currency code. For more, see the urllib3 documentation. data = api_response.text. Web scraping is a technique to extract data from a website.
