I have been playing with exchange_rate(..)

Having called, for example,

exchange_rate("AUDCAD", currency="CAD", counter_currency="AUD")

All good so far.

How do I delete the exchange_rate AUDCAD when I am done with it?


it does not matter                      I think that I shall never see
how much I dig and dig                    A billboard lovely as a tree
this hole just                      Indeed, unless the billboards fall
keeps getting deeper                      I'll never see a tree at all
