Create a Python program that:

• Creates a sales receipt, displays the receipt entries and totals, and saves the receipt entries to a file
  • Prompt the user to enter the
    • Item Name
    • Item Quantity
    • Item Price
  • Display the item name, the quantity, and item price, and the extended price (Item Quantity multiplied by Item Price) after the entry is made
  • Save the item name, quantity, item price, and extended price to a file
    • When you create the file, prompt the user for the name they want to give the file
    • Separate the items saved with commas
    • Each entry should be on a separate line in the text file
  • Ask the user if they have more items to enter
• Once the user has finished entering items
  • Close the file with the items entered
  • Display the sales total
  • If the sales total is more than $100
    • Calculate and display a 10% discount
  • Calculate and display the sales tax using 8% as the sales tax rate
    • The sales tax should be calculated on the sales total after the discount
  • Display the total for the sales receipt

Save the program and submit it to this site for grading.

I have solve the problem in python code with comments and screenshot for easy understanding :)

CODE-

#python code
#Main function
def main():
    #Empty list
    l=[]
    #taking inputs from user
    name=input("Enter item name:")
    quantity=int(input("Enter item quantity:"))
    price=float(input("Enter item price:"))
    #Printing all details of item
    print("name= ",name)
    print("Quantity= ",quantity)
    print("Price= ",price)
    #Calculating and displaying extended price=quantity*price
    e=quantity*price
    #storing extended price of each item in list
    l.append(e)
    print("Extended price= ",e)
    #Taking name of the file as input from user
    f_name=input("Enter the filename in which you want to save data...")
    #opening that file in write mode as calculation is done only on the item
    # stored in one execution of program
  
    file=open("{}.txt".format(f_name),'w')
    #While loop
    while(1):
        #Storing all the details of item in that file with , in between
        file.write(name+",")
        file.write(str(quantity)+",")
        file.write(str(price)+",")
        file.write(str(e)+"\n")
        #Asking user if they wants to add more items
        i=input("Do you want to add more items?(y/n)")
        #if yes then again take input of all details of the items and
        #storing it in file in next iteration of loop as the loop continues
        if(i=="y" or i=="Y"):
            name=input("Enter item name:")
            quantity=int(input("Enter item quantity:"))
            price=float(input("Enter item price:"))
            print("name= ",name)
            print("Quantity= ",quantity)
            print("Price= ",price)
            e=quantity*price
            l.append(e)
            print("Extended price= ",e)
        #otherwise close the file and come out of loop
        elif(i=="n" or i=="N"):
            file.close()
            break
    #Printing total sales stored in that list l
    print("Sales total= ",sum(l))
    #if total sales >$100
    if(sum(l)>100):
        a=sum(l)
        #10% discount
        dis=a/10
        #sales after discount
        sales=a-dis
        #printing discount
        print("Discount= ",dis)
        #8% sales tax on the sale after discount
        sales_tax=sales*8/100
        #printing sales tax
        print("Sales Tax= ",sales_tax)
        #Total sale after discount and sales tax addition
        s=sales+sales_tax
        #Displaying final sales
        print("Total sales after discount and sales tax addition = ",s)
#calling main function
main()
