You need to use

from monster import Monster

otherwise you would need to use

class Dragon(monster.Monster):

for it to work, but the problem is asking for the above example where you use the from monster import Monster statement.

I just tested it in the code challenge and they will actually both work. So you can choose whichever you prefer.

Just to clarify, here would be either code you could use:

import monster

class Dragon(monster.Monster):
    size = 10
from monster import Monster

class Dragon(Monster):
    size = 10

This is because the first import statement is importing the entire monster file so you need to then specify that you want the Monster class from the monster.py file. If you use the from monster import Monster, then you are just importing the Monster class and can refer to it just as Monster.

Thanks for the quick response John Lindsey This solves the issue :)
