How to read a zip file in Python 3 from object storage in Data Science Experience

savezip.py

import zipfile
from io import BytesIO
import requests
import json
import pandas as pd

def get_zip_file(credentials):

    url1 = ''.join(['https://identity.open.softlayer.com', '/v3/auth/tokens']) 
    data = {'auth': {'identity': {'methods': ['password'], 'password': {'user': {'name': credentials['username'],'domain': {'id': credentials['domain_id']}, 'password': credentials['password']}}}}} 
    headers1 = {'Content-Type': 'application/json'} resp1 = requests.post(url=url1, data=json.dumps(data), headers=headers1) 
    resp1_body = resp1.json() 
    for e1 in resp1_body['token']['catalog']:
        if(e1['type']=='object-store'): 
            for e2 in e1['endpoints']:   
                if(e2['interface']=='public'and e2['region']==credentials['region']): url2 = ''.join([e2['url'],'/', credentials['container'], '/', credentials['filename']]) s_subject_token = resp1.headers['x-subject-token'] headers2 = {'X-Auth-Token': s_subject_token, 'accept': 'application/json'} 
    
    s_subject_token = resp1.headers['x-subject-token']
    headers2 = {'X-Auth-Token': s_subject_token, 'accept': 'application/json'}
    r = requests.get(url=url2, headers=headers2, stream=True)
    
    z = zipfile.ZipFile(BytesIO(r.content))
    z.extractall()# save zip contents to disk
    
    return(z)

z = get_zip_file(credentials)
