My company uses Office 365 within OneLogin. Therefore I need to log in to OneLogin first then sign into Office 365 (OneDrive). My question is how do I do the authentication for this in Python? I want to read the excel file stored in OneDrive directly. I tried to retrieve the data directly using python requests module with HTTPBasicAuth and HttpNtlmAuth only to get error 403. What is the correct approach for doing this?
