Flask Templating

Create a new Flask application with the following:

Part 1

  • A base.html template for others to inherit from
  • A route for /person/<name>/<age> which renders a template that displays the name and age entered for the URL. That template should inherit from base.html

Part 2

Refactor your calculator application from before!

  • have a route for /calculate which renders a template called calc.html
  • in calc.html, build a form which has two inputs (one with a name of num1 and another with the name of num2for numbers and a select field with the name of calculation with options for "add", "subract", "multiply" and "divide".
  • When the form is submitted it should make a request to a route called /math
  • In your python file, accept the values from the form and depending on what the request contains, respond with the sum, difference, product or quotient.

Part 3

Create a small application which grabs headlines from Google News by keyword. (This application is based on the Google News web scraper from the web scraping exercises.)

  • This application should consist of two routes, / and /results
  • When the server receives a request to /, it should render an HTML page with a form prompting the user for a keyword (e.g. "California"). Submitting the form should result in a request to /results, with the form input passed in the query string.
  • When the server receives a request to /results, it should do the following:
    1. Grab the keyword from the query string;
    2. Make a request to https://news.google.com, and scrape the respose HTML for all news articles (links and headlines);
    3. Filter out articles whose headlines do not match the keyword passed in from the query string;
    4. Render an HTML page with matching articles (links and headlines) in a list.
