Which method is used to remove an element from a list by its value?

The method used to remove an element from a list by its value is the remove() method. This method searches for the first occurrence of the specified value in the list and removes it. If the value is not found, it raises a ValueError.

This functionality is crucial for list manipulation since there are times when you need to delete an element specifically by its value rather than its index. For instance, if you have a list containing names and you want to remove a specific name, using remove("name") allows you to do just that.

Other methods mentioned serve different purposes: delete() is not a standard Python list method, discard() is used in the context of sets, and pop() removes an element at a specific index (or the last element if no index is specified) rather than by value.
