It's not quite clear what you mean by "get at the individual elements",
so I'll just show you a couple of things you can do to a set, and maybe
one of them comes close to what you need:
from sets import Set
aSet = Set(['Small', 'Extra-small', 'Medium'])
Do something for each element:
for element in aSet:
... print element
...
Small
Extra-small
Medium
Convert the set to list:
list(aSet)
['Small', 'Extra-small', 'Medium']
Test membership in the set:
'Small' in aSet
True
'Banana' in aSet
False
Carsten, thank you (once again ;) for your patience. I didn't know I had to
import something.
Thanks again,
V
Have you bothered to find the help file for your particular version of
Python? In Windows, it's a .chm file, a compiled help file, but I'm
sure the same information is available on other distributions.. Anyway,
sets was a module introduced in Python 2.3, and deprecated in Python
2.6, where it's replaced by the built-in type set. So the answer of
whether you need to import or not depends on what version you're running.
In Python 2.5, it's (untested)
import sets
data = sets.Set(mylist)
In Python 2.6 it's
data = set(mylist)
The name datetime is both a module and a class.
import datetime #import the module
obj = datetime.datetime() #use the class within the module you
just imported
You can find the same information online, at least for version 2.6:
Sometimes I'll use google to find stuff specifically on python.org,
typing the following at the google serarch prompt::
datetime site:python.org
the first link in the results page is:
http://docs.python.org/library/datetime.html
which is the online version of the 2.6.4 help
Other useful links for the 2.6.4 documentation:
http://docs.python.org/modindex.html to search for modules
http://docs.python.org/genindex.html to search for anything
Each of these pages has a "quick search" option. For example, I found
the following page:
http://docs.python.org/library/stdtypes.html#set
