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
