Convert A Mixed Nested Dictionary Into A List

I have a list like this: d1= {'Hiraki': {'Hiraki_2': ['KANG_751']}, 'LakeTaupo': {'LakeTaupo_4': ['KANG_708', 'KANG_785'], 'LakeTaupo_6': ['KANG_785'], 'LakeTaupo_2': ['KANG_751',

Solution 1:

Note that your d1 is a dict, not a list, and that the "nested list" you give as your desired output is not actually valid syntax. A dictionary and a list are not the same thing.

That said, here's how to do the conversion you're attempting in such a way as to handle arbitrarily deep nested dictionaries:

>>>defdict_to_list(d: dict) -> list:...ifisinstance(d, list):...return d...ifisinstance(d, dict):...return [[k, dict_to_list(v)] for k, v in d.items()]...return [d]...>>>d1=  {'Hiraki': {'Hiraki_2': ['KANG_751']}, 'LakeTaupo': {'LakeTaupo_4': ['KANG_708', 'KANG_785'], 'LakeTaupo_6': ['KANG_785'], 'LakeTaupo_2': ['KANG_751', 'KANG_785', 'KANG_785', 'KANG_785'], 'LakeTaupo_3': ['KANG_669', 'KANG_669', 'KANG_708', 'KANG_708', 'KANG_669']}}>>>dict_to_list(d1)
[['Hiraki', [['Hiraki_2', ['KANG_751']]]], ['LakeTaupo', [['LakeTaupo_4', ['KANG_708', 'KANG_785']], ['LakeTaupo_6', ['KANG_785']], ['LakeTaupo_2', ['KANG_751', 'KANG_785', 'KANG_785', 'KANG_785']], ['LakeTaupo_3', ['KANG_669', 'KANG_669', 'KANG_708', 'KANG_708', 'KANG_669']]]]]
