Still trying to get the hang of some python intricacies, but this one
has come up a few times. Beyond the obvious syntactic niceties what
is the difference between importing with and without the "from"
syntax?
Its nice for example to do this -
from socket import *
googleip = gethostbyname("www.g
The difference is a term called "namespace pollution".
the "from socket import *" will place a whole lot of methods into your
global namespace, possibly colliding with other methods / variables you've
defined yourself. For example, if your file contained
x = 5
from foobar import *
and foobar co
Extending on this advice somewhat - is it *ever* correct to "import foobar".
There are countless examples of
import os,sys
etc,etc. Strictly speaking should we always be using "from" to only
get what we know we need?
Thanks,

Yes, it depends how the library was designed. Some are designed so that you
can import some of the library into your global namespace. For example, in
Pygame library, it's accepted to do
import pygame
from pygame.locals import *
This keeps the methods like
pygame.init()
pygame.display.set_mode(

No, the plain
I'm not certain if this is more correctly a bash issue, but it seems logical to
at least start here. What I hope to do is set some standard commands (whenever
I open an interactive python shell) as are outlined in the Python.org tutorial:

The rule of thumb is:
Use the "from module import something" if you're only going to use one
or two functions from the module; onl
