How to read Excel File from AWS in Python 3?

Question

the script below runs without any errors in python 2 but in python 3, I get the following error.

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

    306         raise ValueError(

    819         self._io = stringify_path(io)
    820

--> 350             filepath_or_buffer.seek(0)
    351             self.book = self.load_workbook(filepath_or_buffer)
    352         elif isinstance(filepath_or_buffer, str):
AttributeError: 'StreamingBody' object has no attribute 'seek'

What do I have to change in the below script that it will run in python version 3?

import boto3
from io import StringIO
from boto3 import session
import pandas as pd
import numpy as np

session = boto3.session.Session(region_name='region_xyz')
s3client = session.client('s3' , config=boto3.session.Config(signature_version='s3v4'))
response = s3client.get_object(Bucket='db_region_xyz' , Key='Aaa_bbb/Tester.xlsx')

dataset = pd.read_excel(response['Body'])

Regards

Answer 1

dataset = pd.read_excel(io.BytesIO(response['Body'].read()))
