Tuples consists of a number of values separated by comma and enclosed within parentheses. Tuple is similar to list, values in a list can be changed but not in a tuple.

Output:
['A', 'L', 'S', ''T', 'T']

s = [x **2 for x in range (2,11,2)]
print (s)

s = [ ]
for x in range (6, 11)
a=x**2
s. append (a)
print (s)

(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.

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

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.

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) In Python, a set is another type of collection data type. A'Set is a mutable and an unordered collection of elements without duplicates.
(ii) That means the elements within a set cannot be repeated. This feature used to include membership testing and eliminating duplicate elements. 

Syntax:
# Tuple with n number elements
Tuple_Name (E1, E2, E3.......En)
# Elements of a tuple without parenthesis
Tuple_Name = El, E2, E3 ................. En

Python enables reverse or negative indexing for the list elements. Thus, python lists index in opposite order. The python sets -1 as the index value for the last element in list and -2 for the preceding element and so on. This is called as Reverse Indexing.

A list in Python is known as a "Sequence data type" like strings. It is an ordered collection of values enclosed within square brackets [ ]. Each value of a list is called as element.
