I have a class defined as follows
class M(object):
def __init__(self, **kwargs):
...do_something
and I have the result of argparse.parse_args()
, for example:
> args = parse_args()
> print args
Namespace(value=5, message='test', message_type='email', extra="blah", param="whatever")
I want to pass on the values of this namespace (except message_type
) to create an instance of the class M
. I have tried
M(args)
but got an error
TypeError: __init__() takes exactly 1 argument (2 given)
which I do not understand. How can I
message_type
from the list in args
M(value=5, message='test', extra="blah", param="whatever")
directly.You need to pass in the result of vars(args)
instead:
M(**vars(args))
The vars()
function returns the namespace of the Namespace instance (its __dict__
attribute) as a dictionary.
Inside M.__init__()
, simply ignore the message_type
key.
