Summary  
Removing an element from a list by specifying its value rather than its index, using the list’s remove method.  

General domain of usage  
Inventory management in applications such as games or retail systems.

Previously, we removed items from the inventory by index, but it’s also possible to remove items from the inventory by value.

The inventory can contain objects like ```cat```, ```dog```, ```monkey```, ```chicken```, ```parrot```, etc. So, if you want to remove dog from the inventory, you can simply write ```ninja.inventory.remove("dog")```.
