Tuples and Sets

• Tuples are different from lists they use parenthesis
• They are immmutable and they can't be change or you can't delete a value from it.

x = (1,2,3,4,5)
#Its a tuple

Why use a Tuple

• They are faster than a list.
• They are safer less bugs and problems
• You can also use tuples as the keys in dictionary

Different Methods on Tuples

• .count() to see the repetitive element in the list
• .index()

Sets in Python

• There is no order and they don't have duplicate values
• You can't use index to access the items because there is no order

set = {1,2,3,4}
# This is how a set looks like
a = set{(1,2,3)}

Set Methods

• .add() it is used to add something to a set
• .remove() it is used to remove something from the set
• .discard() It is also used remove the element from the set
• .clear() it removes everything from the set

Mathematical Methods in Sets

• | This symbol represents union
• & This represents intersection

a = {1,2,3,4}
b = {2,3,5}
a | b #This will print {1,2,3,4,5}
a & b # This will print {2,3}

Set Comprehension

• basically its like every other comprehension we have seen

x = {1,2,3,4}
b = {num+2 for num in x}
