string = "Python is awesome"

string[9:3:-1]

• ' si no'

• ' '

• ' si noh'

• 'i no'

my_dict = {

"apple": 5,

"banana": 10,

"brinjal": 30

}

my_dict.items() will give ?

• all the values

• all the keys

• the entire dictionary

• tuple of key value pairs

How can I delete all the items from a set in python ?

my_set = {1,2,3,4,5,6}

• my_set.clear()

• for item in my_set:
    my_set.remove(item)

• for item in my_set:
    my_set.discard(item)

• my_set.discard()

s1 = {3,4,5,6}
s2 = {2,3,9,6,12}
s1.intersection(s2)

• {3, 6}

• {2,3,6}

• {5,9,6}

• {3,4,5,6}

Find the elements in set a that are not in set b

• a - b

• a.union(b)

• a.intersection(b)

• a.symmetric_difference(b)

a = {1,2,3,4,5}
b = {2,3,4,9 , 10}
c = {6,7,8,9}

print(a.isdisjoint(b))
print(b.isdisjoint(c))
print(a.isdisjoint(c))
