Generic 3

5 x 3 = 15

(i) A set is created by placing all the elements separated by comma within a pair of curly brackets. The set( ) function can also used to create sets in Python.
(ii) Syntax:
See Variable = {E1, E2, E3 .......... En}
(iii) Example:
> > > S1 = {1, 2, 3, 'A', 3.14}
> > > print(S1)
{1, 2, 3, 3.14, 'A'}
> > > S2={1, 2, 2, 'A', 3.14}
> > > print(S2)
{1, 2, 'A', 3.14}
In above examples, the set S1 is created with different types of elements without duplicate values. Whereas in the set S2 is created with duplicate values, but Python accepts only one element among the duplications, which means python removed the duplicate value because a set in Python cannot have duplicate elements.

(i) In a list, elements are defined within square brackets, whereas in tuples, they may be enclosed by parenthesis.
(ii) The elements of a tuple can be even defined without parenthesis.
(iii) Whether the elements defined within parenthesis or without parenthesis, there is no differente in it's function.

Output:
(i) 2
(ii) 1
(iii) [12, 12, 36]

Output:
(i) 12, 89, 79, 80
(ii) 12, 79, 80
(iii) []

Output:
(i) ['T', 'N', 'M']
(ii) ['T'
(iii) Error
