Unable to read Excel from SharePoint using office365 with Python

Question

Using this answer, I am attempting to read an Excel document from SharePoint into a pandas dataframe. My code is as follows:

from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.file import File 
import io
import pandas as pd

#target url taken from sharepoint and credentials
url = "https://name1.sharepoint.com/sites/name2/name3/name4.xlsx"
username = '[email protected]'
password = 'Pa55word'

ctx_auth = AuthenticationContext(url)
if ctx_auth.acquire_token_for_user(username, password):
  ctx = ClientContext(url, ctx_auth)
  web = ctx.web
  ctx.load(web)
  ctx.execute_query()
  print("Authentication successful")

response = File.open_binary(ctx, url)

#save data to BytesIO stream
bytes_file_obj = io.BytesIO()
bytes_file_obj.write(response.content)
bytes_file_obj.seek(0) #set file object to start

#read excel file and each sheet into pandas dataframe 
df = pd.read_excel(bytes_file_obj, sheetname = None)

When it gets to the ctx.execute_query() line, I get this error:

ClientRequestException: (None, None, '404 Client Error: Not Found for url: https://name1.sharepoint.com/sites/name2/name3/name4.xlsx/_api/Web')

I have tried different documents, but I get the same response.

In the answer linked at the beginning, the url has a cid parameter, which I am wondering if that is the problem. But I haven't been able to find a value to use as my cid, nor have I been able to find out what a cid is. I think the issue maybe in the url variable, but I'm not exactly sure how. Any suggestions much appreciated!

It seems that the provided url for context generation is incorrect. Please have a try following snnipet:

tenant_url= "https://{tenant}.sharepoint.com"
ctx_auth = AuthenticationContext(tenant_url)

site_url="https://{tenant}.sharepoint.com/sites/{yoursite}"

if ctx_auth.acquire_token_for_user("username","password"):
  request = ClientRequest(ctx_auth)
  options = RequestOptions("{0}/_api/web/".format(site_url))
  options.set_header('Accept', 'application/json')
  options.set_header('Content-Type', 'application/json')
  data = request.execute_request_direct(options)
  s = json.loads(data.content)
  web_title = s['Title']
  print("Web title: " + web_title)
else:
  print(ctx_auth.get_last_error())
