I am not sure I phrased my question exactly right, but here is the code to illustrate:
script.py
from simple_salesforce import Salesforce
sf = Salesforce(login stuff here)
with open(nextObjFile, 'r') as f :
    nextObj = f.read().strip()
simple salesforce has a sf..describe() that I need to pass nextObj into.  Is this possible? I tried sf.nextObj.describe() and that does not work.
