Appending a dictionary with items from a list

Question

Hey guys, i have a short question:
Let's say i have a Dictionary filled with fruits and their quantity, and a list filled with fruits.
Now i want to add the fruits from the list to the dictionary, but i have a problem regarding the quantity.

For example i have
Inventory = {Apple:1, Banana:1, Pineapple:2}
List = [Strawberry,Banana, Banana, Orange]

And this is my code so far
def addToInventory(inventory,addedItems):
for k in addedItems:
inventory.setdefault(k,1)

I have problems with guessing how to increase the quantity of already existing fruits in inventory.

Hope you guys can help me out.

Answer 1

inventory = {'Apple': 1, 'Banana': 1, 'Pineapple': 2}

fruits = ['Strawberry', 'Banana', 'Banana', 'Orange']

print(inventory) # {'Pineapple': 2, 'Apple': 1, 'Banana': 1}

def add_to_basket(basket, stuff):
for element in stuff:
if element in basket.keys():
basket[element] += 1
else:
basket[element] = 1

add_to_basket(inventory, fruits)

print(inventory) # {'Pineapple': 2, 'Orange': 1, 'Apple': 1, 'Banana': 3, 'Strawberry': 1}

This looks so awful in a non-monospaced font :\
