• making flat list out of list of lists in python 23 answers

i trying write function take in number of different lists or tuples arguments , return 1 big list.

def addify(*args):     big_list = list()     iterable in args:         if isinstance(iterable, tuple):             big_list.extend(list(iterable))         else:             big_list.extend(iterable)     return big_list  >>> print addify((1,2,3), [2, 5, 3], (3,1,3), [3, 2344, 3]) [1, 2, 3, 2, 5, 3, 3, 1, 3, 3, 2344, 3] 

i learning args , kwargs, , code working right, seems code simple.

there must better way writing long function check if argument tuple , if add convert list , add on. seems bloated.

itertools.chain looking for:

>>> itertools import chain >>> print list(chain((1,2,3), [2, 5, 3], (3,1,3), [3, 2344, 3])) [1, 2, 3, 2, 5, 3, 3, 1, 3, 3, 2344, 3] 

note: calling list necessary if want list instead of itertools.chain object.
