EOF error?

I'm not sure why my code is throwing an EOF error. When I paste it into workspace, it functions just fine.

suggestinator.py 
#For the sake of the question, it gives me the following error twice.
#ERROR: test_exception_not_raised (__main__.TestRaiseExecution)
#----------------------------------------------------------------------
#Traceback (most recent call last):
#  File "", line 23, in test_exception_not_raised
#  File "/workdir/utils/challenge.py", line 24, in execute_source
#    exec(src)
#  File "", line 1, in 
#EOFError: EOF when reading a line

product_idea = input("What is your product idea's name suggestion?  ")
number_of_characters = len(product_idea)

def suggest(product_idea):
    if number_of_characters < 3:
        raise ValueError("Your idea must be 3 or more characters long.")
    return product_idea + "inator"

try:
    result = suggest(product_idea)
except ValueError as err:
    print("Oh no! Your idea must be a minimum of 3 characters. Please try again!")
else:
    print("Congratulations! Your new product name is: " + "{}".format(result))

Hey Sybil Grey 👋

You'll want to avoid writing code outside of the function. The tests for this challenge are setup to call the suggest function with different values and check if the outcome is the expected value (a string returned or a ValueError raised).

The tests are not expecting any user input or additional suggest calls, so instead of adding logic globally you'll only want to raise the error inside the function. The tests will handle the rest 🙂

def suggest(product_idea):
    if len(product_idea) < 3: 
        raise ValueError("Must be 3 characters or more")
    return product_idea + "inator"

Hope this helps!
