Question: When should I use functions?
When should I use classes?
I wrote my program twice: as a function and as a class (I did so for
educational purposes, to better understand both concepts).
Both programs do exactly the same, and the work neatly. Can you advise
when I should use functions and when it's appropriate to make use of
classes?
Any feedback rgrd. my code? Anything I can improve? Thanks!
# FUNCTION
def ManageFood():
shopping_list = []
prompt = ("Which foods would you like to purchase?\nEnter 'quit' to exit. ")
food = input(prompt)
while food != "quit":
shopping_list.append(food)
food = input(prompt)
print("These are your foods on your shopping list: %s." % ",
".join(shopping_list))
eat_food = []
store_food = []
for food in shopping_list:
print("You bought: %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 for instant consupmtion: %s." % ", " .join(eat_food))
print("Food for storage: %s." % ", " .join(store_food))
