(i) In Python, a dictionary is a mixed collection of elements. Unlike other collection data types such as a list or tuple, the dictionary type stores a key along with its element.
(ii) The keys in a Python dictionary is separated by a colon ( : ) while the commas work as a separator for the elements. The key value pairs are enclosed with curly braces { }.

Output:
['A', 'L', 'S', ''T', 'T']

(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.

(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] ]

A list or Tuple can be converted as set by using set( ) function. This is very simple procedure. First you have to create a list or Tuple then, substitute its variable within set( ) function as argument.
Example:
MyList= [2, 4, 6, 8, 10]
MySet=set(MyList)
print(MySet)
Output:
{2, 4, 6, 8, 10}
