Python: My Orders Tracker P-4



Learning : Pythn, sqlite, Database, SQL
Subject: Create a system to track the orders

In this last part we will write the code to Edit an Order, in editing an order function first we will show all orders and will ask the user to select the one to be EDIT, then we will display that order detail on the screen and ask the user to confirm the action by entering ‘Y’ [our code will handel both y and Y]. We will ask the user about each attribute in the Order details if it need to be change or [Just press Enter to Keep the Current Data], also if the user enter ‘e’ or ‘E’ we will exit from the Editing mode.

Here is the code ..

# Function to Edit an Order

def edit_order():
    os.system('clear')
    print("\n==========[ Edit Orders ]==========")
    
    show_order('yes')
    
    edit_order = input('   Select the Order ID to be Edited. [E to Exit] > ')
    
    if edit_order in ['e','E'] : 
        return
    elif not edit_order.isnumeric() :
        input('\n   You need to enter an Order''s ID [Numeric]. .. Press any Key .. ')
        return 
               
    try:        
        
        c.execute ("select * from orders where o_id ={}".format(edit_order))  
        order_list = c.fetchone() 
        
        if order_list == [] :
            input('\n   ID {} Not Exsist. .. Press any key to continue.  '.format(edit_order))
            return
        
        os.system('clear')
        print("\n==========[ Edit Orders ]==========\n")
        print('\n   Details of the Order you select:\n ')
    
        print(" "*15,"ID: ",order_list[0])  
        print(" "*13,"Date: ",order_list[1])
        print(" "*5,"Order Number: ",order_list[2])
        print(" "*12,"Price: ",order_list[4])
        print(" "*9,"Quantity: ",order_list[5])
        print(" "*3,"Shipment Price: ",order_list[6])
        print(" "*7,"Total Cost:  {:.2f}".format((order_list[4]*order_list[5]) + order_list[6]))
        print(" "*6,"Description: ",order_list[3])
        print(" "*12,"Image:",order_list[8])
        print(" "*13,"Link:",order_list[7])
    
        user_confirm = input("\n\n   You Select to EDIT the above Order, Enter Y to confirm, E to Exit. > ") 
        if user_confirm in ['e','E'] : 
            input('\n   You entered ''E'' to Exit. Nothing  will be change. Press any key. ')
            return 
        
        if user_confirm in ['y','Y'] :
            #To Edit the order..

Finish: Now we have an application that will store and retrieve our simple order data.
Enhancement:
We can do some enhancement in [link and image] data part to show and display them in better way.
