Python Python Basics (2015) Number Game App String length

Having trouble solving this code challenge

Create a new function named just_right that takes a single argument, a string.

If the length of the string is less than five characters, return "Your string is too short".

If the string is longer than five characters, return "Your string is too long".

Otherwise, just return True.

so im not sure if str.len is an actual function.

strlen.py 
def just_right(x):
    x=str.len(5)
    if just_right < x:
        return "Your string is too short"
    if just_right>x:
        return "Your string is too long"
    else:
        return True

Hi Christopher! You've got a few things going on here. First, you've got two if statements. What you should have are an if statement, an elif statement, and an else statement. Also, you're comparing just_right to the value of 5. But just_right is the name of the method you're defining. What you should be comparing is the length of x to 5. But you've now overwritten the value of x coming into the function. Take a look:

def just_right(x):
    if len(x) < 5:
        return "Your string is too short"
    elif len(x) > 5:
        return "Your string is too long"
    else:
        return True

This defines a function named just_right which receives one string named x. If the length of that string is less than 5 we return that the string is too short. Otherwise, if the string length is greater than 5 we return that it's too long. But if it's not either of those (meaning it is exactly equal to 5) then we return True. Indicating, of course, that the string length is "just right".

Hope this helps! :sparkles:

Thank you very much! I'm not sure why I didn't even think of that.
