what exactly is your task ? filter all numbers from a string and append them on its end ?

yes exactly. you write a string composed of a mixture of capital letters, noncapital letters and numbers and it separates them into three groups consisting of either only small letters, capital letters and numbers.

# this could be a start for you , it seperates the lower upper and digits from the string via list comprehension. 
inp = input()
lowerletters = [i for i in inp if i.islower()] 
upperletters = [i for i in inp if i.isupper()] 
numbers = [i for i in inp if i.isdigit()] 
print(lowerletters)
print(upperletters)
print(numbers)
