String length

Hi guys.

I'm working on the string length challage.

strlen.py 
def just_right(treehouse):

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

what i was wrong on my code?

should i use return instead of print? and i keep getting syntax errors too.. :(

The challenge specifies that the values should be returned, so yes, you do have to use return instead of print. Return and print are two very different functions, even though their behavior might seem somewhat similar in the Python REPL.

The issue that causes a syntax error is that you are using the len function on "just_right", which is the name of the function, rather than "treehouse", which is the name of the variable holding the string that will be passed in.

There is a third issue, though it's not so much a coding issue as it is an issue of the code checker being very picky about text output. When you print or return a string on these challenges you often have to type the exact text the challenge is requesting, a single typo no matter how minor will often lead to your code being marked as wrong.

In this case the issue is that you have misspelled the word "too" in this string: "Your string is to short".

Fixing all of those issues leads to this code:

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

Which will pass the challenge.
