Answer 1

Program:

key = []

value = []

n = int(input("Enter number of key value pairs : "))

print("Enter keys : ")

for i in range(0, n):

   k = int(input())

   key.append(k)

print("Enter values : ")    

for i in range(0, n):

   v = int(input())

   value.append(v)

   

dic = {}

for i in key:

   for j in value:

       dic[i] = j

       value.remove(j)

       break  

print("The dictionary is",dic)

print("Length of dictionary is",n)

Output:

Enter number of key value pairs : 3

Enter keys :

23

33

43

Enter values :

32

33

34

The dictionary is {33: 33, 43: 34, 23: 32}

Length of dictionary is 3
