The Error validating credentials due to invalid username or password comes up when trying to upload files to SharePoint by a python script

I am trying to upload files to a SharePoint folder structure which has been already created, I have used two files for this
Config_template:

config = dict()
config('sp_user') = 'abs@xyz.com'
config('sp_password') = 'pass@123'
config('sp_base_path') = 'https://xyz.sharepoint.com'
config('sp_site_name') = '/sites/bootromandhsesecurity/Shared%20Documents/Forms/AllItems.aspx?originalPath=0d66ed181f1&id=%2Fsites%2Fbootromandhsesecurity%2FShared%20Documents%2F%2FSprint3'
config('sp_doc_library') = 'Sprint3'

The next file is sharepoint_upload:

import requests
from shareplum import Office365
from .config_template import config
def up():
    # get data from configuration
    username = config('sp_user')
    password = config('sp_password')
    site_name = config('sp_site_name')
    base_path = config('sp_base_path')
    doc_library = config('sp_doc_library')

    file_name = "TestCaseDatabase\Sprint3_Test_Report.xlsx"

    # Obtain auth cookie
    authcookie = Office365(base_path, username=username, password=password).GetCookies()
    session = requests.Session()
    session.cookies = authcookie
    session.headers.update({'user-agent': 'python_bite/v1'})
    session.headers.update({'accept': 'application/json;odata=verbose'})

   
    session.headers.update({'X-RequestDigest': 'FormDigestValue'})
    response = session.post( url=base_path + "/sites/" + site_name + "/_api/web/GetFolderByServerRelativeUrl('" + doc_library + "')/Files/add(url='a.txt',overwrite=true)",
                            data="")
    session.headers.update({'X-RequestDigest': response.headers('X-RequestDigest')})

    # perform the actual upload
    with open( file_name, 'rb') as file_input:
        try: 
            response = session.post( 
                url=base_path + "/sites/" + site_name + "/_api/web/GetFolderByServerRelativeUrl('" + doc_library + "')/Files/add(url='" 
                + file_name + "',overwrite=true)",
                data=file_input)
        except Exception as err: 
            print("Some error occurred: " + str(err))

The username and password have been changed here for security reasons, but when the correct details have been given,

Error authenticating against Office 365. Error from Office 365:’, ‘AADSTS50126: Error validating credentials due to invalid username or password

The above error occurs. Where am I going wrong?

P.S – I have been using Microsoft authenticator for logging into the SharePoint folder, where I need to approve my login on my mobile, is that causing the problem?
