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)

env create by virtualenv will refer to the main env, how did it find
the main env, is there any configuration files, if yes, where is it?

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:

exit()
Upon execution, the log was as follows:

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

Not quite. That makes L1 & L2 tuples.

No, as Chris already answered, unary * is used for packing and unpacking
positional arguments to functions; unary ** is similarly used for

Perhaps you should explain what you are trying to do. If you want to give
instances their own name, why not just give them an instance
attribute "name"? D
