#the items are stored in a dictonary,the format of the dictionary is as follows:
# the key values in the dictionary, store the item names as item ids and the value is a list
# [1500, 50, "static\images\Acrylic Sheild.jpg"] at the index 0 we have the item's price, on the first index we have stored the amount of item in the inventory
# at the 2 index we have passed a string that stores the relative path for the image of the item, this was done so that in the html file
# we can apply a loop that runs through this inventory and displays all the items stored in the inventory automatically
