Write a Python program to find the length of a dictionary.

If input is: {“England”: “London”, “Italy”: “Rome”} then output should be: 2

If input is: {10: “ten”, 20: “twenty”, 30: “thirty”} then output should be: 3

If input is: {} then output should be: 0

Solution

d = eval(input("Enter a dictionary: "))

print("Length of dictionary:", len(d))

Output

Input: {"England": "London", "Italy": "Rome"}

Output: Length of dictionary: 2

Input: {10: "ten", 20: "twenty", 30: "thirty"}

Output: Length of dictionary: 3
