agreed. i was specifically showing how to reverse the loop.
using the much-better-suited Counter class:


from collections import Counter

s=input("Enter a string, eg(4856w23874): ")

checkS=['0','1','2','3','4','5','6','7','8','9']

cnt = Counter()

for char in s:
    cnt[char] += 1

for char, tally in sorted(cnt.items()):
    if char in checkS and tally > 0:
        if tally == 1:
            print(char,"occurs 1 time.")
        else:
            print(char, "occurs", tally,"times.")

>>>
Enter a string, eg(4856w23874): 192398209asdfbc12903348955
0 occurs 2 times.
1 occurs 2 times.
2 occurs 3 times.
3 occurs 3 times.
4 occurs 1 time.
5 occurs 2 times.
8 occurs 2 times.
9 occurs 5 times.
