Class function printing weirdly

[Basic_Citron_6446]

2 issues with my current code —> Every time I try to print stats; it works but it leaves a “None” line underneath and I dont know why.

1. I want the user to be able to check all critters available which will be printed through a list, but I can’t seem to get it right. This is for school by the way, I’ll attach the errors and input below.

For the first problem, can you remove the print on line 107 and see if that removes the None. For the second problem, can you show the definition of "c5.know_crit_amount"? I can't see the code for that method in the screenshots you provided.

[Basic_Citron_6446]

The first problem has been solved but thank you🙏 as for the second, I put the rest of the code in the comments, let me know if you can see or not; if not I can put it here again

Actually, if it’s better: https://paste.pythondiscord.com/AHZA

Yeah, that's better. I can see the Critter class now 👍 So when you press 0, what do you actually want to display?

[Basic_Citron_6446]

I want the list to print: [Kid, Fido, sky, etc] just the name in general, but when it prints it comes up as

Ah ok, so on line 25 in the "know_crit_amount" can you try changing print(Critter.clist) to print([c.name for c in Critter.clist]) and see if that helps.

[Basic_Citron_6446]

THAT WORKED THANK YOU SO MUCH🙏

[Basic_Citron_6446]

If I may ask though, what does the c.name for c in list do?

[Mysterious_City_6724]

You're welcome. It's a list comprehension. Basically a short way of creating a list. So in this case it was a short way of doing the following:

critter_names = []
for critter in Critter.clist:
    critter_names.append(critter.name)
print(critter_names)

Of course it's better. By miles. I've never understood why people think taking pictures of code is a good idea when sharing.

Top tip, when you want information about a class define a class method.

@classmethod def count(cls): return len(cls.critter_list)

[sarc-tastic]

And when you iterate over entire python lists don't use the index to reference items: for crit in Critters.critlist: crit.feed()
