def mang (grocerystock):
mangchoice=int(input("What would you like to do? \n 1):Add a new product to the list? \n 2): Remove a product from the list? \n 3: Change the quantity of an item \n 4): Change the price of an item \n 5): View items and their quantity and price"))
if mangchoice == 1:
infile=open("grocery_stock.txt", 'a')
name=input("Please enter the new product's name would you like to add:")
quant=int(input("Please enter the new product's quantity"))
price=float(input("Please enter the new product's price"))
grocerystock[0]=name
grocerystock[1]=quant
grocerystock[2]=price
gS=str(grocerystock)
gs=gS.strip("[',']")
infile.write(gs + '\n')
if mangchoice == 2:
namedelete=input("what item would you like to remove")
a=open("grocery_stock.txt", 'r')
data_list= a.readlines()
a.close()
print (data_list)
del data_list[namedelete]
b= open ("grocery_stock.txt", 'w')
b.writelines(data_list)
b.close()
def intro():
choice=(int(input("Would you like to go to Managerial mode or Shop mode?(press 1 for Managerial and 2 for shop mode, to quit press 3)")))
