Confused about a program about finding factors

I was searching the web about finding factors and saw the one below I was confused about it and wanted some help I don't know what it means

This is for a project that we are making which is to make a game to find factors in which users have to input a number and the program will show the factors I've tried putting 

   if ValueError:
        print("Sorry, I didn't understand that.")

but it doesn't work, I wanted the program to say "Sorry, I didn't understand that." if the user typed a letter or special character

how do I loop it too if the user typed a letter or special character

   def print_factors(x):
      print("The factors of",x,"are:")
      for i in range(1, x + 1):
      if x % i == 0:
         print(i)

    num = int(input("Enter a number: "))

    print_factors(num)

the program works but I can't seem to add loops and the value error thing on the top

You can use try catch block, and catch the valueError exception. Like below

def print_factors(x):
    print("The factors of",x,"are:")
    for i in range(1, x + 1):
        if x % i == 0:
            print(i)


try:
    num = int(input("Enter a number: "))
    print_factors(num)
except ValueError:
    print("Sorry, I didn't understand that.");
