I keep on getting an File "", line 4, in EOFError: EOF when read however I can't find the error, am I missing something?

suggestinator.py 
def suggest(product_idea):
    return product_idea + "inator"
try:
    product_name = input("what is your idea?   ")
    if len(product_name) <= 3:
        raise ValueError  
except ValueError as err:
    print("to little characters entered{}".format(err))

else:
    print(suggest(product_name))

OWEN LINES - Hi, I think you're overthinking what you've been asked to do. In essence all you're being asked is to do a check against product_idea to see if it is less than 3 characters. So this should be < and not <= as this is 3 or less. The return statement will hold the output from the function, so this is a bit confusing as this actually will go at the end. Your code goes in between the function definition and the return statement.

To pass the challenge, you don't need to code an input so remove this code:

product_name = input("what is your idea?   ")

also, the entire TRY/EXCEPT block is not needed and is incorrectly indented. The IF/ELSE is good enough, but you're missing the ELSE part, which would be the return statement. Finally, keep an eye on your indenting to make sure things are in the right place. Using an online code compiler/checker is really useful as it tells you if the indentation is incorrect. ​

In summary,

  1. Insert your code between the function name and return statement.
  2. An IF statement to check if product_idea is less than 3 characters.
  3. If it is below 3, raise your ValueError
  4. An ELSE statement that uses the original return statement from the challenge.

The code below passes the challenge if you want the answer.

def suggest(product_idea):
   ​if len(product_idea) <= 3:
       ​raise ValueError
   ​else:
       ​return product_idea + "inator"

**** Update **** It seems there might be an error with the challenge. The text says is less than 3 characters long which should mean that the code has to be <. But actually, the challenge also passes with <=. Just for info.

ugggggghhhhh i spent hours on this and this is the only thing that works

def suggest(product_idea): if len(product_idea) < 3: raise ValueError("please enter more than 2 characters") return product_idea + "inator"

why does this code work but none of the others do? i don't know man i just bashed my head against the keyboard for hours hoping it would work. if i use else/elif/try or literally any other keywords it returns a syntax error. but if you haven't found the answer yet this will get you through lol.
