How to correctly formulate an exception?

Question

Python

How to correctly formulate an exception when it is necessary that the value be given in all cases except those that end in 11

a=int(input())
if a==1:
    print(a, 'программист')
b=a%10
c=a%100
if (b==1 and (c!=11)):
    print(a, 'программист')

Answer 1

Maybe you should not turn the input number into int. Let there be a line. You can then write s.endswith('11').
