'Using a function to determine weather a list and a tuple both with variables match

i have a tuple within a tuple:

 meals = (
\# name of dish \[0\], ingredients \[1\]
 ("fish_sticks", ("frozen fish", "potatoes", "mustard")),
("chicken_curry", ("chicken", "curry paste", "carrots", "potatoes", "rice")),
("chicken_veg", ("chicken", "potatoes", "carrots")),
("pasta", ("spaghetti", "tomato sauce"))

I have to return a true/false depending on if what I have in my fridge = the meal, to see if I can make it.

This is where I started:

def meal_list(meal, ingridients_list):
    for item in meal: 
        if meal == ingridients_list:
            print("true")
        else:
            print("false")
    return meal_list("fishsticks",("frozen fish", "potatoes", "mustard") )

I do realize that I have no list to show the code what is right and wrong. just dong know how to get going.

You have to check if ALL ingredients needed to make the meal are in your ingridients_list. Currently, you print immediately after the first iteration of the loop (which isn't structured correctly).

Try:

def meal_list(meal, ingridients_list):
    #get all the ingredients for the meal
    needed = [i for m, i in meals if m==meal][0]

    #check if items needed are in your ingredients
    for item in needed:
        if item not in ingridients_list:
            return False
    return True

>>> meal_list("fish_sticks",("frozen fish", "potatoes", "mustard"))
True
