What might cause my sample program to forget that already imported datetime?

And if you don't like doing datetime.datatime all the time, you can also do

from MODULE import SYMBOL

and do

from MODULE import SYMBOL as ALIAS

when you get conflicts.

The big issue is that you lose control with * as it pulls 'arbitrary'
things into your name space.

I do sometimes do things like the combination

import MODULE

from MODULE import SYMBOL

if there is some name in the module I want to use a lot.

I don't see much need for:

import MODULE

from MODULE import *

as if you are bringing in ALL the names into the current module name
space, when will you need to use the module.symbol notation?
