For this assignment you will be creating a very small flask application. Your application should:
- have a route for
/welcome, which responds with the string "welcome" - have a route for
/welcome/home, which responds with the string "welcome home" - have a route for
/welcome/back, which responds with the string "welcome back"
Add another route to /sum and inside the function which sends a response, create a variable called sum which is equal to 5+5. Respond with the sum variable.
