I keep getting an "unresolved reference" error even though I made a statement to it.

```
verb_dict = {"say": say, "examine": examine}

```

The error is after the `examine`:

```
def examine(noun):
    if noun in GameObject.objects:
        return GameObject.objects[noun].get_desc()
    else:
        return "There is no {}".format(noun)

```

Did I do something wrong when coding it? 

I am also using pycharm community edition.
