dictionary - Python - converting string key to integer -

i have dictionary in following order. dictionary dynamically generated using from collections import defaultdict

ref = defaultdict(<type 'list'>, {'344': [('0', '0', '136'),  ('548', '136', '137'),  ('548', '136', '6')],         '345': [('0', '0', '136'), ('548', '136', '137'),  ('548', '136', '6'),  ('742', '136', '6')]} 

what tried:

from here

ref = {int(k):[int(i) in v] k,v in ref.items()} 

but error:

typeerror: int() argument must string or number, not 'tuple' 

what want:

i want convert keys , values in string integers

ref = defaultdict(<type 'list'>, {344: [(0, 0, 136),      (548, 136, 137),      (548, 136, 6)],             345: [(0, 0, 136), (548, 136, 137),      (548, 136, 6),      (742, 136, 6)]} 

your values list , items tuple need convert tuples items int,you can use map function :

ref = {int(k):[map(int,i) in v] k,v in ref.items()} 

and if in python 3 can use generator expression within tuple :

ref = {int(k):[tuple(int(t) t in i) in v] k,v in ref.items()} 

also since map returns list if want result tuple can use recipe too.
