Sort Integers in String

The program must accept a string S which has only numbers and underscores as the input. The program must print only the integers present in the string S sorted in ascending order.

Boundary Condition(s):
2 <= Length of the string S <= 100

Input Format:
The first line contains the string S.

Output Format:
The first line contains the list of numbers sorted in ascending order.

Example Input/Output 1:
Input:
15_17_185_76_3_61_

Output:
3 15 17 61 76 185

Example Input/Output 2:
Input:
_5_98_15_17_185_76_3_61_

Output:
3 5 15 17 61 76 98 185

for i in n:
    if i.isdigit():
        s+=i
    else:

            s=""
if s!="":
    k.append(int(s))
