del list_name[index] # To delete single value del list_name # To delete whole list
[1, 2, 2, 3, 4, 5] [1, 2, 2, 3, 4] [2, 2, 3, 4]
The remove() method removes the first matching value from the list.
[1, 2, 2, 3, 4, 5] [1, 2, 3, 4, 5] [1, 2, 3, 4]
The pop() method like del deletes value at a particular index. But pop() method returns deleted value from the list.
[1, 2, 3, 3, 4, 5] [1, 2, 3, 3, 4] [2, 3, 3, 4]
