Why is it "obvious"?

What is "this"? Are you referring to the function, to the mainline 
program, or what?

One improvement - response.lower().startswith("yes") will cover all your 
cases.

You can collect functions in a sequence, then iterate over it. This 
allows for easy expansion (when you decide to add another function).

funcs = (dosomething(), dosomethingelse())
for func in funcs:
   getid()
   func()
