Use del and specify the index of the element you want to delete.

You can use the pop() method to remove specific elements of a list.

EXAMPLE:

a=[1,2,3,4,5,5]
a.pop(2)

OUTPUT:  3

pop() method takes the index value as a parameter and removes the element at the specified index. Therefore, a[2] contains 3 and pop() removes and returns the same as output. You can also use negative index values.

EXAMPLE:

a=[1,2,3,4,5,5]
a.pop(-1)

OUTPUT:  5

Delete the List and its element:

We have multiple functions for deleting the List’s element with different functionality. 

  • del function helps to delete the list variable from code.
  • pop function helps to delete the individual element according to positioning of the list. Return the position value.
  • remove function helps to delete the first occurrence of the number or string mentioned in its arguments.
  • Clear function clear the all elements present in the list without delete its variable.
  • #Program:
    >>> a=[1,2,3,4,5,"sahil"]
    >>> a.pop(0)# delete element at position 0
    1
    >>> a
    [2, 3, 4, 5, 'sahil']
    >>> a.remove(2)# delete element 2 that present at 0 position
    >>> a
    [3, 4, 5, 'sahil']
    >>> del a[1:3] # delete multiple elements from list at position 1 to 2
    >>> a
    [3, 'sahil']
    >>> a.clear()# clear the list
    >>> a
    []
    >>> del a #delete the variable a
    >>> a
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    NameError: name 'a' is not defined
