移除Python中嵌套字典键的外部

def remove_nested_keys(dictionary):
    for key, value in list(dictionary.items()):
        if isinstance(value, dict):
            dictionary.pop(key)
            dictionary.update(value)
            remove_nested_keys(dictionary)
    return dictionary

# 示例用法
nested_dict = {
    'a': 1,
    'b': {
        'c': 2,
        'd': {
            'e': 3
        }
    }
}

result = remove_nested_keys(nested_dict)
print(result)

{'a': 1, 'c': 2, 'e': 3}
