# Drain Capping Take your drain method from the [previous exercise](drain-method.md) and prevent it from being drained below a volume of `0`. ### What is expected ```python tub = Bathtub("white", 20) tub.drain(15) print(tub.current_volume) # should be 5 tub.drain(15) print(tub.current_volume) # should be 0, NOT -10 ``` --- ©2021 Daniel Gallo
