- dict dicts dictionary concat
- 0 (after 0 ratings)
Wanted a simple function to concatenate n dictionaries. Each dictionary passed in is deep copied to avoid any possible mutation of dictionaries being concatenated.
Dictionary m's key/values will be overwritten by dictionary m+1's key/values.
1 2 3 4 5 6 7 8
import copy def dict_concat(*args): """Concatinates a new dictionary without any side effects""" cursor = iter(args) d_final = copy.deepcopy(cursor.next()) for d in cursor: d_final.update(copy.deepcopy(d)) return d_final
