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.

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
