At Café Pandasia, the coffee shop tracks its coffee bean inventory. The data is stored in a pandas.Series that keeps track of the quantity of each coffee bean type (coffee_inventory);

The café manager has noticed a mistake in the inventory of "Robusta" beans — it was recorded as 200, but after a recount, it should actually be 180.

• Modify the coffee_inventory and set the Robusta beans to 180.
