Answer :-

a = input("Enter a string = ")
sum = 0
digit = ""

for i in a :
    if i.isdigit() :
        sum += int(i)
        digit += i
        
if sum == 0 and len(digit) == 0:
    print(a, "has no digit")
else :
    print("Original string = ", a)
    print("Digits are ", digit)
    print("Sum of all digit = ", sum)

Output :-

Enter a string = abc000
Original string =  abc000
Digits are  000
Sum of all digit =  0
>>> 

Enter a string = Path058 Walla93
Original string =  Path058 Walla93
Digits are  05893
Sum of all digit =  25
>>>
