2.1: "NameError: name 'is_hungry' is not defined" yet I pass the test

My code:

# Class definition
class Animal(object):
    """Makes cute animals."""
    # For initializing our instance objects
    def __init__(self, name, age, is_hungry):
        self.name = name
        self.age = age
        self.is_hungry = is_hungry

# Note that self is only used in the __init__()
# function definition; we don't need to pass it
# to our instance objects.

zebra = Animal("Jeffrey", 2, True)
giraffe = Animal("Bruce", 1, False)
panda = Animal("Chad", 7, True)

print zebra.name, zebra.age, zebra.is_hungry
print giraffe.name, giraffe.age, giraffe.is_hungry
print panda.name, panda.age, panda.is_hungry

Returns:

Traceback (most recent call last):
  File "python", line 2, in <module>
  File "python", line 8, in Animal
NameError: name 'is_hungry' is not defined

I still pass the excercise but that’s annoying cause I can’t see the code in action.

Same here: it must be some trouble with the validator that I’m going to report now.

You seem to have the correct code, so rest assured and go on :)

Oh, on a side note it is just a matter of indentantion: cancelling the indentation at line 8, then riputting the tabs just works fine.

When I copy&paste the code into the exercise (on the old interface), it validates as correct.

The only way I could get this to validate without error was to convert all the indents to spaces in an external editor and then paste back in. Goddamn editor and style inconsistencies! XO

I had to cancel all the indentation and input it again, but that fixed it :)

Strange, as navigating it, it looked like all tabs…

Giacomo Sorbi almost 11 years

I think it had some space hidden among tabs. Just guessing, though.

Thanks for letting me know about the indentation. Did you report this to the buggy exercises group?

Daniel Seymour almost 11 years

PS All that was for Giacomo.

Giacomo Sorbi almost 11 years

Yeah, we already discussed it in the buggy exercise group: it appears it happens with some old exercise when switching to the new UI.

It is the problem of the indentation from line 2 to 8.

Giacomo Sorbi almost 11 years

Well, try doing tabula rasa: completely cancel every indentation and put it anew, so to fix it.

I find this problem is about the space area at the line 2,3,4,5, I delete the space,and use Enter at the line 2,3,4,5 ,this problem is solved.

Giacomo: I’m having the same problem, and I wasn’t able to fix it by deleting the existing indentation at line 8 and then inserting the tabs. It isn’t critical, but it is irritating… half the fun is solving the problem, and the other half is seeing the code work ;) Ciao! Daniel

I tried just now and it works fine to me: try checking also other indentations, particularly on line 7.

Yes the problem was with the indentation. I had to fix everything that is indented. I see this problem often when I copy some code from the classes course and paste it in Codecademy Labs. Codecademy Labs always has problem with the indentation of code in this course it seems.
