- Build and run a Flask application on your computer.
- Manipulate and test the structure of a request object.
- Web Framework: software that is designed to support the development of web applications. Web frameworks provide built-in tools for generating web servers, turning Python objects into HTML, and more.
- Extension: a package or module that adds functionality to a Flask application that it does not have by default.
- Request: an attempt by one machine to contact another over the internet.
- Client: an application or machine that accesses services being provided by a server through the internet.
- Web Server: a combination of software and hardware that uses Hypertext Transfer Protocol (HTTP) and other protocols to respond to requests made over the internet.
- Web Server Gateway Interface (WSGI): an interface between web servers and applications.
- Template Engine: software that takes in strings with tokenized values, replacing the tokens with their values as output in a web browser.
This is a test-driven lab. Run pipenv install to create your virtual
environment and pipenv shell to enter the virtual environment. Then run
pytest -x to run your tests. Use these instructions and pytest's error
messages to complete your work in the app/ folder.
Instructions begin here:
- Design a Flask application that carries out basic Python functions using routing and views.
- Your
index()view should be routed to at the base URL with/. It should Contain anh1element that contains the title of this application, "Python Operations with Flask Routing and Views". - A
print_stringview should take one parameter, a string. It should print the string in the console and display it in the web browser. Its URL should be of the format/print/parameter. - A
count()view should take one parameter, an integer. It should display all numbers in therangeof that parameter on separate lines. Its URL should be of the format/count/parameter. - A
math()view should take three parameters:num1,operation, andnum2. It must perform the appropriate operation on the two numbers in the order that they are presented. The included operations should be:+,-,*,div(/would change the URL path), and%. Its URL should be of the format/math/parameters.
Once all of your tests are passing, commit and push your work using git to
submit.
