Converting list to *args in Python

Question

In Python, how do I convert a list to *args?

I need to know because the function

scikits.timeseries.lib.reportlib.Report.__init__(*args)

wants several time_series objects passed as *args, whereas I have a list of timeseries objects.

Any help is greatly appreciated :)

Answer 1

Have you tried:

timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)

(notice the * before timeseries_list)

Answer 2

*args just means that the function takes a number of arguments, generally of the same type.

Check out this section in the Python tutorial for more info.

Answer 3

yes, using *arg passing args to a func will make python unpack the values in arg and pass it to the func...

so:

>>> def printer(*args):
 print args


>>> printer(2,3,4)
(2, 3, 4)
>>> printer(*range(2, 5))
(2, 3, 4)
>>> printer(range(2, 5))
([2, 3, 4],)
>>>
