I wasn't the one who answered your question; I just pointed out that you
were a bit rude to the one who did.

I was not critiquing those solutions (though the frequent use of "from x
import *" statements should be avoided), I'm pointing out a
misconception that you might have about name lookup:

When python encounters an expression like this:

a()

It does two things:

1. It looks up the object associated with the name "a"
2. It calls that object

That is why Python said that a name/variable could not be found and not
a function; step one is only concerned with name lookup, it doesn't know
anything about the name's usage context.
