It expands the list into the arguments. It's the parallel to:
def func(*args):
which collapses the args into a list.

Hi Chris,
Thanks for the reply.
However, the error occurs even if I don't do anything, that is, even if I
simply import the library and exit() after that.
I created a file a.py whose contents were the following:
import pyossim
exit()
Upon execution, the log was as follows:

You don't need doing something special, each decorator returns a new
function that and only the result function formed by all decorators will
be run. Consider this:
def clear_cache(func):
def decorator(*args, **kwargs):
print "cache cleared"
return func(*args, **kwargs)
At first i have a python environment, after using virtualenv test
command, a new environment named test is created, in that directory
have some of the executable commands
such as python.exe, so can i program without the main installation of python?
