List operations

1. Modify the list

>>> name['Frank', 'Lee', 2, ['Andy', 'Troy']]>>> name[0] = "Frank Bian">>> name['Frank Bian', 'Lee', 2, ['Andy', 'Troy']]

2. List insertion

>>> Name ['Frank by', 'lil', 2, ['andy ', 'troy'] >>> name. insert (1, "Marlon") # The value under the inserted position is the value >>> name ['Frank by', 'marlon ', 'lil', 2, ['andy ', 'troy']

3. append object to end)

>>> name['Frank Bian', 'Marlon', 'Lee', 2, ['Andy', 'Troy']]>>> help(name.append)>>> help(name.append)>>> name.append('Duff')>>> name['Frank Bian', 'Marlon', 'Lee', 2, ['Andy', 'Troy'], 'Duff']

4. Delete the list element (L. remove (value)-> None -- remove first occurrence of value.
Raises ValueError if the value is not present .)

>>> name.append('Duff')>>> name['Frank Bian', 'Marlon', 'Lee', 2, ['Andy', 'Troy'], 'Duff', 'Duff']>>> name.remove('Duff')>>> name['Frank Bian', 'Marlon', 'Lee', 2, ['Andy', 'Troy'], 'Duff']
