thanks for your feedback! @boB
I wrote a function that does exactly what I want, and that is:
Create a shopping list and then let the user decide which items (food)
are supposed to be instantly consumed and which ones stored.
def ManageFood():
create_shopping_list = []
prompt = ("Which foods would you like to purchase?\nEnter 'quit' to exit. ")
food = input(prompt)
while food != "quit":
create_shopping_list.append(food)
food = input(prompt)
print("These are your foods on your shopping list: %s." % ", "
.join(create_shopping_list))
eat_food = []
store_food = []
for food in create_shopping_list:
print("You bought this item: %s. " % (food))
prompt = input("What would you like to do with it?\nEnter
'eat' or 'store'. ")
if prompt == "eat":
eat_food.append(food)
elif prompt == "store":
store_food.append(food)
print("Food you want to eat now: %s." % ", " .join(eat_food))
print("Food you want to store: %s." % ", " .join(store_food))
ManageFood()
PS: Please let me know if you have any suggestions how to write my
code above in a shorter, more elegant fashion (it does what it's
supposed to do, but not sure if a pro would write it same way I did).
Besides that, I want to take it a step further and rewrite the
function above as a class, and I don't know how exactly how to do
this.
(coding newbie pains ... I just learned the basics about classes in
Python, but nowhere could I find examples of how to properly
initialize classes, given that it operates solely with user input -
same goes with with calling that class properly). Here's how far I got
on my own:
class FoodShopping(object):
def __init__ (self, create_shoppping_list, prompt, food, eat_food,
store_food):
self.create_shopping_list = create_shopping_list
self.prompt = prompt
self.food = food
self.eat_food = eat_food
self.store_food = store_food
def ManageFood(self, create_shopping_list, prompt, food, eat_food,
store_food):
create_shopping_list = []
prompt = ("Which foods would you like to purchase?\nEnter
'quit' to exit. ")
food = input(prompt)
while food != "quit":
create_shopping_list.append(food)
food = input(prompt)
print("These are your foods on your shopping list: %s." % ", "
.join(create_shopping_list))
eat_food = []
store_food = []
for food in create_shopping_list:
print("You bought this item: %s. " % (food))
prompt = input("What would you like to do with it?\nEnter
'eat' or 'store'. ")
if prompt == "eat":
eat_food.append(food)
elif prompt == "store":
store_food.append(food)
print("Food you want to eat now: %s." % (eat_food))
print("Food you want to store: %s." % (store_food))
FoodShopping()
That's the error message I get when executing my code:
