Python转换嵌套字典，其中列表包含作为单个元素的浮动元素

nested_dict = {
    'key1': 'value1',
    'key2': [
        {'nested_key1': 'nested_value1'},
        {'nested_key2': 'nested_value2'}
    ]
}

def flatten_dict(nested_dict):
    flattened_dict = {}
    for key, value in nested_dict.items():
        if isinstance(value, list):
            for i, item in enumerate(value):
                if isinstance(item, dict):
                    for nested_key, nested_value in item.items():
                        flattened_dict[f'{key}_{i}_{nested_key}'] = nested_value
        elif isinstance(value, dict):
            nested_flattened_dict = flatten_dict(value)
            for nested_key, nested_value in nested_flattened_dict.items():
                flattened_dict[f'{key}_{nested_key}'] = nested_value
        else:
            flattened_dict[key] = value
    return flattened_dict

flattened_dict = flatten_dict(nested_dict)
print(flattened_dict)

{
    'key1': 'value1',
    'key2_0_nested_key1': 'nested_value1',
    'key2_1_nested_key2': 'nested_value2'
}
