from... import...

[fatwallet961@yahoo.com]

what's the from ... import keyword use for?
for example - from contenttype import getContentType

import os
import sys
import getopt
import types
import re
import pprint
import logging
from contenttype import getContentType

In Java what kind of statement is similar this?

thanks

Try:

importing_modul es.html

http://www.python.org/doc/current/tut/

node8.html#SECT ION008100000000 000000000

And more generally maybe:

Happy coding - Paddy.

The program now can access attributes as follows:

foo = sys.argv[1]
bar = logging.getLogg er()
baz = getContentType( )

In other words, use 'from spam import eggs' when you want to refer to
'eggs' instead of 'spam.eggs'. In the specific case you cite, probably
the programmer knows they only want to access one attribute --
'getContentType ' -- and would rather use that name for ease of reading
rather than the longer 'contenttype.ge tContentType'.

It's for this reason that many of the standard library modules have
relatively short names, eight characters or less. It has the result
that 'import spam' followed by access to 'spam.eggs' is both clear,
and easy enough to read.

To learn more, read about Python namespaces.
