I'm having an issue with dict and list: I have a function that ask user for an input, can be multiple items. The function allows only items that I have in a dict Once I get the input, I need to look for the value of each key (item) I'm trying to extract each element of the list and have multiple variables (I tried with tuple) but when I try to look for the value of each key with .get() the output is none
def main():
i = tuple(user_item())
*#use tuple to avoid TypeError unhashable list*
print(i)
*#I use the print statement here to help debugging
#the output is: ('Name_item', )
#which means that it founds the item in my user_item function*
print(items.get(i))
*#output is none, also tried:* print(items.get("i")) = output None
def user_item():
order = []
while True:
try:
i = input("Item: ").title()
if i in items:
order.append(i)
continue
except EOFError:
return order
main()
The problem is that the variable i in main() is actually a tuple not a string. So, when you do items.get(i) it returns None as the dict has no tuple as keys but strings! Try instead:
for key in i:
print(items.get(key))
Also there is no need to do i = tuple(user_item()): since user_item() returns a list, you can just have i = user_item(). This with the previous code should fix also the error "TypeError unhashable list".
