[Tutor] Class methods

[michael scott]

Just to add a little to Alexandre's answer.  You can keep most of the code the same just add in   
            farmlet[0].eat()
            farmlet[1].eat()

and it will be okay... kinda. Or you could rewrite it and  do it another way...  I'm guessing that you are using python 3 by your print statements, so I don't think you need the int() around your input, even in python.2x input() was safe for numbers I believe (the whole list will rip my throat out if I'm wrong anyways, lol), but in your while loop around line 82 you have all the conditions responding to a string, even thought you explicitly changed the input to an integer.

if choice == "0"


instead of 


if choice == 0:

so I got a continual output of 
('\nSorry, but', 3, "isn't a valid choice.")  

Now this does not get your program running the way you want it to, but it will start you off making the corrections you need. Just some things to think about, 
in line 113, when did you define class f?
in line 102, what are you trying to do, and are you telling it the right thing?
since you have 2 (or possibly more) critters you are taking care of, how does the player know which one he is feeding / talking to / playing with in your farmlet?

Anyways best of luck in your program, sounds pretty cool...

What is it about you... that intrigues me so?

David,

You want to call .talk() on your "critter" instance which has the
.talk() method, not on farmlet (which is a list as the error message
states)

> Traceback (most recent call last):
>   File "I:/Python/programs/critter_farm4.py", line 117, in <module>
>     main()
>   File "I:/Python/programs/critter_farm4.py", line 103, in main
>     farmlet.talk()
> AttributeError: 'list' object has no attribute 'talk'

You will probably have a problem when calling talk() because it
references to the "farmlet" variable which doesn't exist in the scope
of your .talk() method.
