1.
(r’^articles/(\d{4})/(\d{2})/$’, month_archive)
vs.
2.
(r’^articles/(?P<year>\d{4})/(?P<month>\d{2})/$’, month_archive)
The first one: positional argument
The second one: keyword argument
For example, a request to
/articles/2009/10/
would result in
1. month_archive (request, ’2009′,’10′)
2. month_archive(request, year=’2009′, month=’10′)
def func(*args, **kwargs):
Python functions and methods can pass and receive arguments in two forms:
1. positional argument (the order is important)
2. keyword argument(names along with the values)
—
In Python, list and dictionary types are used for positional and keyword arguments respectively.
Passing a list as an argument and prefixing it with a single asterisk(*) will cause each item of the list in order. This will be used as a separate positional argument.
Passing a dictionary and prefixing it two asterisks(**) will cause the keys of the dictionary to be used as names for separate keyword arugments and the dictionary’s values to become the values of these arguments.
