Python如何高效地处理复杂的嵌套字典

def process_nested_dict(dictionary):
    for key, value in dictionary.items():
        if isinstance(value, dict):
            process_nested_dict(value)
        else:
            # 对当前的键值对进行处理
            # ...

nested_dict = {'a': {'b': 1, 'c': {'d': 2}}, 'e': 3}
flat_list = [value for inner_dict in nested_dict.values() for value in inner_dict.values()]
# 对展开后的列表进行处理
# ...

def flatten_dict(dictionary):
    for key, value in dictionary.items():
        if isinstance(value, dict):
            yield from flatten_dict(value)
        else:
            yield value

nested_dict = {'a': {'b': 1, 'c': {'d': 2}}, 'e': 3}
flat_generator = flatten_dict(nested_dict)
# 逐个处理生成器中的数据
# ...
