Question

I need help building code in python for this:

Create a 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

Answer 1

#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()
