QuantLib users.

I'm trying to use ql.IborIndex(...) using this example but for USD currency. However, I receive a type error of the following. How can I use this instead of ql.USDLibor(...)? Thank you.

To create an instance of the currency class you have to call it:

Try ql.USDCurrency() instead of ql.USDCurrency

You can check this site for references on object construction for the QuantLib Python module.
