In this article, we will discuss how to convert a nested OrderedDict to dict? Before this we must go through some concepts:
In Python, the OrderedDict
class is a subclass of the built-in dict
class that maintains the order of the keys added to it. A nested OrderedDict
is a collection of OrderedDicts
that can be represented as a tree-like structure. Sometimes, it may be necessary to convert a nested OrderedDict
to a regular dict
. This can be achieved using a recursive function that iterates through the nested structure and converts each OrderedDict
to a regular dict
.
Here is an example Python program that converts a nested OrderedDict
to a regular dict
:
from collections import OrderedDict def convert_nested_ordereddict_to_dict(nested_ordereddict): if isinstance(nested_ordereddict, OrderedDict): return dict((k, convert_nested_ordereddict_to_dict(v)) for k, v in nested_ordereddict.items()) elif isinstance(nested_ordereddict, list): return [convert_nested_ordereddict_to_dict(x) for x in nested_ordereddict] else: return nested_ordereddict
In this program, the convert_nested_ordereddict_to_dict
function takes a nested OrderedDict
as an argument and returns a regular dict
. If the input is an OrderedDict
, the function recursively calls itself to convert each nested OrderedDict
to a regular dict
. If the input is a list, the function iterates through the list and converts each element using the same recursive approach. If the input is not an OrderedDict
or a list, it returns the input unchanged
