Question

For removing a specified element from a collection, What method can be used?

1) remove()
2) delete()
3) pop()
4)iscard()

Answer 1

To remove an element from a collection, the method remove() is used in many programming languages. Delete() is not a standard collection method, pop() removes by index and also returns the element, while discard() is specific to Python sets and doesn't raise an error if the element is not found.

Step-by-step explanation:

To remove a specified element from a collection, the method remove() can be used. This method is generally available in many programming languages, including Python and Java. For instance, in Python, if you have a list, you can remove elements by their value using list.remove(value), and in Java, you can use Collection.remove(object) to remove the first occurrence of the specified element from the collection.

It's worth noting that delete() is not a universal method for collections, and pop() is typically used to remove an item by its index (and it also returns the removed element). In Python sets, the discard() method is similar to remove(), but it will not raise an error if the element is not found in the set.
