Flask is a highly used Python micro Web Framework. It provides basic functionality to build web applications, like routing, request/response handling, etc. It's a "small" framework compared to other ones (like Django), but in many cases that's a great advantage.

Fork this repo and create a new cloud9 workspace as we do with other projects. Then follow the usual steps:

$ mkvirtualenv flask-practice -p /usr/bin/python3
$ pip install -r requirements.txt

Flask framework provides, out of the box, a way to run a development web server in your local machine. Just execute the run_app.py script available in the project and the application will stay listening at localhost:8080. (Make sure to have all the requirements previously installed)

$ python run_app.py

Tests are split among several functions. You can run them all together doing pytest tests.py or select individual based on keyword expressions like pytest -k 'test_1' tests.py.

This view was done for you as an example. Just implemented a basic view on / URL that returns a string welcoming to your Flask practice

This one was also done as an example. In this case, the view receives two numbers as URL parameters, and returns the sum of them in a formatted string.

i.e: Sending /sum/100/200, the response would be: "The sum of 100 and 200 is: 300"

In this case, you'll have to implement a view that receives user's first name and last name, and builds its lowercase username using first letter of the first name, concatenated with the last name. (Remember to validate that given parameters are strings)

i.e: Sending /username/Elon/Musk will return emusk

For this exercise, you'll have to implement a view that receives a ?search= query parameter in the URL, and returns the amount of users in the given users_list that contains that search string in their names.

i.e: /user?search=mo will return 'Found 2 users that match with search "mo"'
