Python 如何解析amazon lambda响应['Body'中的数据

我正在使用aws lambda加载存储在s3中的csv文件，如何逐行读取响应的内容，就像从csv.reader读取一样

Lambda函数：

import urllib
import boto3

print('Loading function')

s3 = boto3.client('s3')

def lambda_handler(event, context):
    bucket = event['Records'][0]['s3']['bucket']['name']
    key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key'].encode('utf8'))

    response = s3.get_object(Bucket=bucket, Key=key)
    content = response['Body'].read()

    #read content line by line as a list

content.splitlines适合您吗

for line in content.splitlines():
    # do something with line

for line in content.splitlines():
    # do something with line
