The core Python language is fairly small, and a weekend spent with a good tutorial can teach you everything you'll need for daily tasks; similarly, the parts of Django you'll use most often can be picked up pretty quickly and without much more than basic Python knowledge. As you go forward, developing a good working knowledge of Python's standard library and some of the web-oriented third-party modules (particularly things like BeautifulSoup[1], feedparser[2] and httplib2[3], and dateutil[4] even though it's not really directed at the "web") will pay big dividends, as will exploration of some of Python's more advanced features (understanding how Django model classes work internally, for example, isn't necessary for working with Django, but if you ever want to extend the system you'll need to dig into metaprogramming and desriptors). Probably the best introduction to Python for those who already have some programming experience is Mark Pilgrim's "Dive Into Python"[5]; it goes pretty quickly and the examples move from Python basics to useful advanced topics.

Re: How well should I know Python before using Django?
As someone who jumped in as new to python, and django both. I'd say
you won't have much trouble, if you're comfortable with another
language. You can start out knowing nothing about it, but you'll need
some basics pretty quickly. Things about Python that I wish I'd
focused on before starting with django...
Lists, and List comprehensions. [(m.id,m.name) for m in Model] for
example
None,[],{},'',False, and NULL. Little things, but hard to track down
if you misuse.
Reference. Everything is by reference, so when modifying variables
keep that in mind. or it can hurt.
Dictionaries. .copy() and .deepcopy(). Everything is by reference!
** in front of a dict can expand it so you can use a dict to generate
function
keyword arguments: fuction(a=1,b=2,c=3) is the same as dict={'a':1,'b':
2,'c':3} and then function(**dict). This is really handy. Keys are
any immutable object, so you can even do things like use a class
definition or a function as a key.
dict.get('name',value_if_not_present).
When things get evaluated. Most things get evaluated when the module
is loaded, not on every view. So if you are doing dynamic choices for
example it takes a little different approach since defining them in
the class definition will only evaluate them once when the class is
first interpreted, not each time an instance is created.
class __init__(*args,**kwargs), and super(). You'll need them. args
is a tuple of non-keyword, kwargs is a dict. Any changes you want
done to a class, but on a per-instance basis are done here. Like
specifying dynamic choices.
iPython. First thing after django you should install. Specifically
the dir and vars functions which let you inspect objects
interactively, and even write/test code snippets before putting them
in your project.
Django code. Don't be afraid of it, it's well commented and not
nearly as complicated as you might expect. It really helped me to
look at the newforms library, looking up pythonisms that I didn't
understand.
tuples: ('value') is not the same as ('value',). Always toss in that
trailing comma.

I was (and really still am) an utter newb to python. Then again, I think I've proven that more than I'd like.
