This.

I have some code that imports multiprocessing.connection and I do
actually type out multiprocessing.connection.Client and it doesn't
bother me one bit. Code is read a lot more than it is written, even if
only one person ever sees it. The whole "less typing" thing is absurd,
especially when IDEs have completion features and stdlib modules share
similar or exact function names (is it subprocess.Popen or os.popen? I
guess the author wanted to save 2 seconds typing while anyone who reads
it has to spend 5-10 to find out which is being used) . I've been using
full namespaces since I started learning Python, and I even do it at the
interactive interpreter because it's just a habit. IMO, "from foo import
*" should only ever be used for /intentional/ namespace pollution (and
even then, there are probably better ways to do it).
