I'm currently stuck at the very first hurdle trying to get the Refinitiv Eikon API working with Python.

My code:

import eikon as ek # the Eikon Python wrapper package

import numpy as np # NumPy

import pandas as pd # pandas

import configparser as cp

print(ek.__version__)

ek.set_app_key('my app key here')

The response from this I get is:

AttributeError                            Traceback (most recent call last)

If someone could offer some help I'd be very grateful, thanks
