Is this a great formula for a hot network question or is it trolling the SE network?
Here's a generic and easily repeatable formula for questions that could be asked on probably any site in the Stack Exchange network:

2. I have ruled out the obvious answer for arbitrary/bad reasons.
3. What do I do?

"""Remove redundancy and give function names meaning when using the route decorator.
def home():
return 'hello'
def profile(username):
