OAuth2 Token 401 Unauthorised

I have managed to get a token from oauth2 in my python app. However when I try and get some results I get a 401. Below is my code.

    crmapi = "https://{orgname}.api.crm4.dynamics.com/api/data/v9.1/"
    logging.info('Python HTTP trigger function processed a request.')

    crmorg = 'https://{orgname}.crm4.dynamics.com/'
    clientid = '0e91010b-...….'
    username = username
    userpassword = 'password'
    tokenendpoint = 'login.microsoftonline.com/.../token
    crmwebapi = 'https://{orgname}.api.crm4.dynamics.com/api/data/v9.1'
    crmwebapiquery = '/opportunities(8A49E258-...….)'
    tokenpost = {
    'client_id':clientid,
    'username':username,
    'password':userpassword,
    'grant_type':'password',
    'client_secret': '........',
    'scope':'https://{orgname}.crm.dynamics.com//user_impersonation'
    }
    tokenres = requests.post(tokenendpoint, data=tokenpost)
    accesstoken = ''
    try:
        accesstoken = tokenres.json()['access_token']
    except(KeyError):
        #handle any missing key errors
        print('Could not get access token')

    if(accesstoken!=''):
        #prepare the crm request headers
        crmrequestheaders = {
            'Authorization': 'Bearer ' + accesstoken,
            'OData-MaxVersion': '4.0',
            'OData-Version': '4.0',
            'Accept': 'application/json',
            'Content-Type': 'application/json; charset=utf-8',
            'Prefer': 'odata.maxpagesize=500',
            'Prefer': 'odata.include-annotations=OData.Community.Display.V1.FormattedValue'
        }
        crmres = requests.get(crmwebapi+crmwebapiquery, headers=crmrequestheaders)
