Retrieve values from a frozen set dictionary (python)

Question

I have a frozen set dictionary of the form:

{frozenset({12345, 3245}): 45.95948791503906,
 frozenset({12345, 12804138}): 48.996036529541016,
 frozenset({3245, 9876}): 50.67853927612305,

Is it possible for me to iterate over the values based on one of the key from the frozenset?

Example:

If I provide the value 12345, I want to return

frozenset({12345, 3245}): 45.95948791503906,
frozenset({12345, 12804138}): 48.996036529541016

If I provide the value 3245, I want to return

frozenset({12345, 3245}): 45.95948791503906, frozenset({3245, 9876}): 50.67853927612305

Basically, I want to iterate based one of the key from the multikey frozen set dictionary

Answer 1

You can try:

my_dict = {frozenset({12345, 3245}): 45.95948791503906,
 frozenset({12345, 12804138}): 48.996036529541016,
 frozenset({3245, 9876}): 50.67853927612305}



def retrieve_dict(number_I_want):
  final = []
  for key, value in my_dict.items():
    for i in key:
      if i == number_I_want:
        final.append(key)
  print(final)

retrieve_dict(12345)
