(i) List is an ordered set of elements. But, a dictionary is a data structure that is used for matching one element (Key) with another (Value).
(ii) The index values can be used to access a particular element. But, in dictionary key represents index. Remember that, key may be a nunmber of a string.
(iii)  Lists are used to look up a value whereas a dictionary is used to take one value and look up another value.

Set Operations :
(i) Union : It includes all elements from two or more sets.
(ii) Intersection : It includes the common elements in two sets.
(iii) Difference : It includes all elements that are in first set (say set A) but not in the second set (say set B).
(iv) Symmetric difference : It includes all the elements that are in two sets (say sets A and B) but not the one that are common to two sets.

Sort ( ) :
It sorts the element in list.
Syntax :
   List.sort(reverse=True|False,key=myfunc)
Sorts the element in list :
Both arguments are optional
(i) If reverse is set as True, list sorting is in descending order.
(ii) Ascending is default.
(iii) Key=myFunc; "myFunc" - the name of the user defined function that specifies the sorting criteria.
Example :
MyList = [Thilothamma', "Tharani', 'Anitha','SaiSree', 'Lavanya')
MyList.sort( )
print(MyList)
MyList.sort(reverse=True)
print(MyList)
Output :
['Anitha', 'Lavanya', 'SaiSree', 'Tharani', 'Thilothamma']
['Thilothamma', 'Tharani', 'SaiSree', 'Lavanya', 'Anitha']
 

(i) The elements of a list are changeable (mutable) whereas the elements of a tuple are unchangeable (immutable), this is the key difference between tuples and list.
(ii) The elements of a list are enclosed within square brackets[ ]. But the elements of a tuple are enclosed by parenthesis().
(iii) Iterating tuples is faster than list.
