Hello Douglas,



It seems that you missed adding the arguments inside the "UnitedStates" function. 



For example, it should be of the following format for NYSE calendar:

calendar2 = ql.UnitedStates(ql.UnitedStates.NYSE) 

You can check the documentation here: https://quantlib-python-docs.readthedocs.io/en/latest/dates.html#calendar

Hope this helps.
