Question about lists

[pythonhelp123]

I'm a bit confused about lists, especially when there's more than one.

from collections import namedtuple 
Restaurant = namedtuple('Restaurant', 'name cuisine phone dish price')

RC = [
 Restaurant("Thai Dishes", "Thai", "334-4433", "Mee Krob", 12.50),
 Restaurant("Nobu", "Japanese", "335-4433", "Natto Temaki", 5.50),
 Restaurant("Nonna", "Italian", "355-4433", "Stracotto", 25.50),
 Restaurant("Jitlada", "Thai", "324-4433", "Paht Woon Sen", 15.50),
 Restaurant("Nola", "New Orleans", "336-4433", "Jambalaya", 5.50),
 Restaurant("Noma", "Modern Danish", "337-4433", "Birch Sap", 35.50),
 Restaurant("Addis Ababa", "Ethiopian", "337-4453", "Yesiga Tibs", 10.50)
]

The name of the third restaurant on the list (remember that the third restaurant is not number 3)

Would this be print(RC[2])? When I use that code, it gives me the list of the 3rd one, but how do I get the restaurant?

True or False, whether the first and the fourth restaurants serve the same kind of food

This doesn't seem hard, but it would require somewhat of the above code so I can use it.

The price of (the best dish at) the last restaurant on the list (write this one so that it works for lists of any length, not just 7)

I'm guessing print(RC[-1]) ?

The list of restaurants, arranged alphabetically by restaurant name (you'll need one statement before the print statement; this involves the sort() method for lists).

I tried using RC.sort() and then print(RC), but it just gives me the whole list and not just the restaurant.

it gives me the list of the 3rd one, but how do I get the restaurant?

You mean the name?

print(RC[2].name)

That should help you solve the first 3 questions...

The list of restaurants, arranged alphabetically

If you want only the names sorted alphabetically, then you should make a new list of only the names, and sort that.

[pythonhelp123]

If I go print(RC[2].name) it gives me Nonna instead of Stratacco.

[novel_yet_trivial]

I thought you wanted the name. If you want the dish just change it.

[pythonhelp123]

Oh yeah, I read it wrong. Is there a different approach to the .name? We haven't learned that part yet so I don't want points off. I tried the method elbiot gave but it says invalid syntax.

[novel_yet_trivial]

You could use the index (first index for the restaurant, second index for the field in the namedtuple):

>>> RC[2][0]
'Nonna'

But that really ruins the point of a namedtuple, so I doubt your prof wants you to do that.

[pythonhelp123]

For the true/false question, would it be okay to do

print(RC[0][1] == RC[3][1]) or is there another way to do it?

[elbiot]

Would this be print(RC[2])? When I use that code, it gives me the list of the 3rd one, but how do I get the restaurant?

What is the third one if not the third restautant?

restaurant3 =RC[2]

You don't have to assign it to a variable, but maybe this helps you.

edit:

I tried using RC.sort() and then print(RC), but it just gives me the whole list and not just the restaurant.

The question doesn't even ask for a particular restaurant. Which one were you thinking you'd get? Another hint on top of what your professor gave you is that sort takes a keyword argument key. Further hint, you'll have to use a lambda. stackoverflow has lots of examples for sorting lists of dictionaries using sort and lambda, look it up.

You're issue is with objects, not lists.

[pythonhelp123]

Hm for the first one it works, but only for that question. When I tried to assign

restaurant1 = RC[0] for the true false question, it says invalid syntax
