Python - Constructors and Object Initialization

What will this code print?

class Animal:
    def __init__(self, species='Dog'):
        self.species = species

animal1 = Animal()
animal2 = Animal('Cat')
print(animal1.species, animal2.species)

AError: missing argument

Final Answer:
Dog Cat -> Option D
Quick Check:
Default parameter works = D [OK]

Quick Trick: Default parameters fill in missing arguments automatically [OK]

Common Mistakes:

Assuming missing argument causes error
Mixing order of printed species
Ignoring default parameter values
