P.S. I think it's a problem with re.search,because it doesn't work only when I input there one number twice,in one str.

Answer 1

If you change the line with re.search to:
if all(n in nums for n in num):
...I think it works for you.

Answer 2

# KUMURUKE cc Do you mean like that;
try:
num=int(input("enter some numbers or some letters: "))
print(num)
print("a number")
except ValueError:
print("not a number")

Answer 3

thank you for responses guys,i've fixed it. There was num instead of n:D
