Your error in in line 66 (which is not shown), but you need to call the method load_alien in one of two (possibly more) ways
1. If the method that is calling load_alien is in the same class, call with self.load_alien(lair)
2. if called from another class, you need to call as <class>.load_alien(lair)
this will require creating an instance to the class you are calline, for example
[code]
my_class_name = Alien()
# then to call method
my_class_name.load_alien(lair)
