Output:

Username:gakkos
Password:2323
Successfully logged in! 
Welcome, gakkos Please choose one of the following options by entering the corresponding menu number.

recapping/learning while providing solution , wont mind if someone will correct me, i appreciate that.
i assume you hv done this in python 2.x (raw_input function available) so i left out the brackets in print statement.
i added while and break statement so the code will keep asking for correct username & password

For security, the program should ask the password previous to cheking the login name, otherwise an attacker could find valid login names.

that is normal

menu=True
while menu:
    print ("""
                                1.Search for a product.
                                2.See Basket
                                3.Check Out
                                4.Logout
                                5.Exit
                                """)
    answer = raw_input("Your choice: ")


    if answer=="1":


                        message3=raw_input("Please select which item you want to add to your basket (Enter 0 for main menu): ")

                        for key,value in inventory.items():
                            if key in inventory.items():
                                print "found",value,"similar items"

                            elif message3 in key:
                                print key, ":", value

ı have to create menü but it can't see my code. ı changed little bit but doesn't work when ı change item in inventory program can not add basket when ı chhose 2 in menü.

[ka06059]

few lines need to recheck...
if key in inventory.items(): is always false, so your code will never execute the print "found",value,"similar items" statement.

nothing is wrong withelif message3 in key: but i prefer elif message3 == key: depend on how we view the code
