(i) pop() function: pope () function can also be used to delete an element using the given index value. pop () function deletes and returns the last element of a list if the index is not given
(ii) clear ( ) function: The function clear( ) is used to delete all the elements in list, it deletes only the elements and retains the list.

The remove( ) function can also be used to delete one or more elements if the index value is not known.

Syntax:
del List [index of an element]
# to delete a particular element
del List [index from : index to]
# to delete multiple elements
del List
# to delete entire list

Syntax:
List.append (element to be added)
List.extend ([elements to be added])

(i) To include an element at your desired position, you can use insert ( ) function. The insert( ) function is used to insert an element at any position of a list.
(ii) Syntax:
List.insert (position index, element)

In Python, append( ) function is used to add a single element and extend( ) function is used to add more than one element to an existing list.

list = [2,4,6]
list [0:3] = [1,3,5]
for x in list:
print (x)
Output: 1
3
5

Syntax:
Lise Variable [index of an element] = Value to be changed
Lise Variable [index from: index to] = Values to be changed

Syntax:
for index_var in list:
print (index_ var)

MySubject = ["Physics", "Chemistry", "Biology"]
i = 0
while i < len(MySubject):
print (MySubject[i])
i = i + 1

Marks = [10, 23, 41, 75]
i= -1
while i >= -4:
print (Marks[i])
i = i+-1
Output:
75
41
23
10

(i) i = 0
(ii) <
(iii) Marks [i]
(iv) i + 1

(i) Mylist contains another list as an element. This type of list is known as "Nested List': Nested list is a list containing another list as an element.
(ii) Example: Mylist = [ "Welcome", 3.14, 10, [2,4,6] ]

Syntax:
Variable = [element-1, element-2, element-3 ................ elernent-n]
Example:
Marks = [10,23,41,75]
Fruits = ["Apple", "Orange", "Mango",  "Banana"]
MyList = [ ]

Python programming language has four collections of data types such as List, Tuples, Set and Dictionary.
