Three methods for deleting the Python list: code sharing and python
1. Use the del statement to delete an element.
>>> i1 = ["a",'b','c','d'] >>> del i1[0]>>> print(i1)['b', 'c', 'd']>>>
After the del statement deletes a value from the list, it will no longer be accessible.
2. Use pop () to delete Elements
Pop () deletes the element at the end of the list and all
