Taking user input and storing that to a variable then storing that variable to a list

[wavic]

I gave you an example.
Define the function, and just use it when you have to input some data.

items = []
if (option=="1"):
    print "we will now enter the information for this item"
    items.append(user_input())

If that is not some school assignment consider to learning Python 3 instead of v2. The time is not going back

Oh ok so it does the same thing i have done with

item_number = raw_input("what is the item number ")
item_name = raw_input("what is the name of this item? ")
item_price = raw_input("how much does this item cost? ")

but with the function i can use it anywhere else i need to instead of typing all this stuff again

That is the functions purpose.
