my_dict1 = {'a':1, 'chk':{'b':2, 'c':3}, 'e':{'chk':{'f':5, 'g':6}} }

I would like to loop through the dict recursively and if the key is 'chk', split it.
Expected output:

{'a':1, 'b':2, 'e':{'f':5}}
{'a':1, 'c':3, 'e':{'f':5}}
{'a':1, 'b':2, 'e':{'g':6}}
{'a':1, 'c':3, 'e':{'g':6}}

Not sure of how to achieve this. Please help.
What I have tried is below.

temp_list =[]
for k,v in my_dict1.iteritems():temp ={}if k is "chk":for key,val in v.iteritems():temp[key] = valmy_dict1[k]={}for ky,vl in temp.iteritems():my_new_dict = copy.deepcopy(my_dict1)for k,v in my_new_dict.iteritems():if k is "chk":my_new_dict[k] = {ky:vl}temp_list.append(my_new_dict)
print temp_list

output:

[{'a': 1, 'chk': ('c', 3), 'e': {'chk': {'f': 5, 'g': 6}}},{'a': 1, 'chk': ('b', 2), 'e': {'chk': {'f': 5, 'g': 6}}}]

How to make it recursive?

from itertools import productmy_dict = {'a':1, 'chk':{'b':2, 'c':3}, 'e':{'chk':{'f':5, 'g':6}} }def process(d):to_product = []  # [[('a', 1)], [('b', 2), ('c', 3)], ...]for k, v in d.items():if k == 'chk':to_product.append([(k2, v2) for d2 in process(v) for k2, v2 in d2.items()])elif isinstance(v, dict):to_product.append([(k, d2) for d2 in process(v)])else:to_product.append([(k, v)])lst = [dict(l) for l in product(*to_product)]unique = [][unique.append(item) for item in lst if item not in unique]return uniquefor i in process(my_dict):print(i)# {'e': {'f': 5}, 'b': 2, 'a': 1}
# {'e': {'g': 6}, 'b': 2, 'a': 1}
# {'e': {'f': 5}, 'a': 1, 'c': 3}
# {'e': {'g': 6}, 'a': 1, 'c': 3}
