Answer 1

Using pandas 0.20.3

import os
import boto3
import pandas as pd
import sys

if sys.version_info[0] < 3: 
    from StringIO import StringIO # Python 2.x
else:
    from io import StringIO # Python 3.x

# get your credentials from environment variables
aws_id = os.environ['AWS_ID']
aws_secret = os.environ['AWS_SECRET']

client = boto3.client('s3', aws_access_key_id=aws_id,
        aws_secret_access_key=aws_secret)

bucket_name = 'my_bucket'

object_key = 'my_file.csv'
csv_obj = client.get_object(Bucket=bucket_name, Key=object_key)
body = csv_obj['Body']
csv_string = body.read().decode('utf-8')

df = pd.read_csv(StringIO(csv_string))
