How to add items from a list as values to corresponding dictionary key?

Question

I want to sort groceries from an shopping list into categories using a dictionary.

I have created the following 4 lists:

DAIRY= ["milk", "cheese", "butter"]

MEAT= ["steak", "ham", "sausage"]

VEG= ["broccoli", "tomato", "carrot", "eggplant"]

FRUIT = ["apples", "bananas", "oranges"]

and the following dictionary :
Shopping_List = {"VEG": [], "FRUIT": [], "MEAT": [], "DAIRY": [], "OTHER": []}

When a word from the input list matches an element on one of the 4 lists, I want it to be added as a value to the corresponding key in the dictionary, e.g if the input is "bananas",which is an element of the list FRUIT, I want it to be added as a value for the dictionary key FRUIT {"FRUIT": ["bananas"]}.

Furthermore, If the input word isn't on any of the lists,f it should be added as a value for the dictionary key OTHER.

My goal is to create a function that does the following:

With an input list,such as, this :
input_list: ["bananas", "broccoli","carrot", "egg", "steak", "milk", "cookies", "water"]

the function groceries (input_list) should return the following dictionary:

{"VEG": ["carrot", "broccoli"], "FRUIT": ["bananas"], "MEAT": ["steak"], "DAIRY": ["milk"], "OTHER": ["cookies", "eggs", "water"]}.

I am currently stuck as I don't know how to add the items from the input list to the empty value list of the matching dictionary key.

I would really appreciate it if someone could give me some pointers.

Answer 1

dict["VEG"] =[it for it in VEG if it in input_list]

Answer 3

DAIRY= ["milk", "cheese", "butter"]

MEAT= ["steak", "ham", "sausage"]

VEG= ["broccoli", "tomato", "carrot", "eggplant"]

FRUIT = ["apples", "bananas", "oranges"]

input_list = ["bananas", "broccoli","carrot", "egg", "steak", "milk", "cookies", "water"]

d = {x : [] for x in ['FRUIT','DAIRY','MEAT', 'VEG']}

for item in input_list:
if item in FRUIT:
d['FRUIT'].append(item)
if item in DAIRY:
d['DAIRY' ].append(item)
if item in VEG:
d['VEG' ].append(item)
if item in MEAT:
d['MEAT' ].append(item)

print(d)

Answer 4

DAIRY= ["milk", "cheese", "butter"]

MEAT= ["steak", "ham", "sausage"]

VEG= ["broccoli", "tomato", "carrot", "eggplant"]

FRUIT = ["apples", "bananas", "oranges"]

input_list = ["bananas", "broccoli","carrot", "egg", "steak", "milk", "cookies", "water"]

d = {x : [] for x in ['FRUIT','DAIRY','MEAT', 'VEG']}

for item in input_list:
for name in ['FRUIT','DAIRY','MEAT', 'VEG']:
if item in globals()[name]:
d[name].append(item)

print(d)

Answer 5

If you store categories in the dictonary instead of separate lists you get flexibility without any tricks such as searching variables names in globals.

Extending by adding product price. But one problem, for uncategorized products I had to use a generic price.
