num=input('Enter the digit =')

>> Enter the digit = 111122233333

from collections import Counter

for key,value in Counter(list(num)).items():
    print('{x} occur {y}-times'.format(x=key,y=value))

>>1 occur 4-times
2 occur 3-times
3 occur 5-times

Q. Write a program to remove the punctuation marks from the string given by the user
