Python - PEP8 悬挂缩进错误信息

Question

对于以下代码，我收到以下错误：

config = {
    'bucket': json.loads(record['body'])
                ['Records'][0]['s3']['bucket']['name'],
    'key': json.loads(record['body'])
           ['Records'][0]['s3']['object']['key']
}

E131 continuation line unaligned for hanging indent
                              ['Records'][0]['s3']['bucket']['name'],

E131 continuation line unaligned for hanging indent
                           ['Records'][0]['s3']['object']['key']

我已经尝试了一些选项，包括以下 - 但它不起作用：

config = {
    'bucket': json.loads(
                        record['body']
                        )
                        ['Records'][0]['s3']['bucket']['name'],
    'key': json.loads(record['body'])
           ['Records'][0]['s3']['object']['key']
}

我也试过在行尾 + \ 但也不起作用

Answer 1

试试这个，应该是这个格式

config = {
    'bucket': json.loads(record['body'])['Records'][0]['s3']['bucket']['name'],
    'key': json.loads(record['body'])['Records'][0]['s3']['object']['key']
}

或在此，

config = {
    'bucket': json.loads(record['body']) \
                ['Records'][0]['s3']['bucket']['name'],
    'key': json.loads(record['body']) \
           ['Records'][0]['s3']['object']['key']
}

Answer 2

为了符合 PEP8，以下适用于此场景：

config = {
    'bucket': json.loads(record['body'])
    ['Records'][0]['s3']['bucket']['name'],

    'key': json.loads(record['body'])
    ['Records'][0]['s3']['object']['key']
}
