You have the following piece of code:  
java script:

```python
var enemies = hero.findEnemies();
if (enemies)
    hero.say('So many enemies!');
else
    hero.say('No enemies!');

```

or python:

```python
enemies = hero.findEnemies()
if enemies:
    hero.say('So many enemies!')
else:
    hero.say('No enemies!')

```

**What will hero say if there are no enemies?**

You can test the it in [https://codecombat.com/play/level/logical-path](https://codecombat.com/play/level/logical-path)? for python or  
in [https://codecombat.com/play/level/logical-path?codeLanguage=javascript](https://codecombat.com/play/level/logical-path?codeLanguage=javascript) for java script.  
You don’t need to be logged in, no glasses needed for hero.findEnemies() in any level in codecombat.  
Simply comment the default ( or your ) code and paste the above code.

The hero will say “So many enemies!”, since the enemies array exists, even if there are no enemies

And how the code must be rewritten to work as intended? ( question not to @SuperSmacker , I know he knows the answer 😉 )

The easiest way I can think of (python)…

Yes, this is the way this check must be done. ( if enemies.length \> 0: will also work in CoCo python )  
I have made a search in topics and there are many examples where this error is present. But the catch is the CoCo python isn’t acting as a real python.  
If there are no enemies the answer must be **‘No enemies!’**  **after if enemies:** in real python.
