What it seems like to me is that by calling the keys method you re returning to python a dictionary object when it s looking for a list or a tuple  So try taking all of the keys in the dictionary  putting them into a list and then using the for loop

From the error  I infer that referenceElement is a dictionary  see repro below   A dictionary cannot be hashed and therefore cannot be used as a key to another dictionary  or itself for that matter      gt  gt  gt  d1  d2           gt  gt  gt  d1 d2    1 Traceback  most recent call last     File   lt input gt    line 1  in  lt module gt  TypeError  unhashable type   dict    You probably meant either for element in referenceElement keys   or for element in json  referenceElement   keys    With more context on what types json and referenceElement are and what they contain  we will be able to better help you if neither solution works
