Python: Find the digits which are absent in a given mobile number

Python Basic - 1: Exercise-25 with Solution

Write a Python program to find the digits which are absent in a given mobile number.

Sample Solution:

Python Code:

def absent_digits(n):
  all_nums = set([0,1,2,3,4,5,6,7,8,9])
  n = set([int(i) for i in n])
  n = n.symmetric_difference(all_nums)
  n = sorted(n)
  return n
print(absent_digits([9,8,3,2,2,0,9,7,6,3]))

Sample Output:

[1, 4, 5]
