2. Sale of Salgados by Shifts¶

2.1. Afternoon / Evening Salgados Sale¶

def save_transaction(price, credit_card, description):
   file = open('transactions.txt',"a")
   file.write("%16s%07d%16s\n" %(credit_card,price*100,description))
   file.close()

items = ["Esfiha","Coxinha","Pastel","Cheese bread"]
prices = [1.50,2.20,1.80,1.20]
running = True

while running:
   option = 1
   for item in items:
      print(str(option) + "." + item)
      option += 1
   print(str(option) + ".Finish")
   choice = int(input("Choose an option: "))
   if choice == option:
      #the last option, Finish
      running = False
   else:
      card = input("Credit card number: ")
      save_transaction(prices[choice-1],card,items[choice-1])

Corrected format by the student!

2.2. Morning Salgados Sale¶

def save_transaction(price, credit_card, description):
   file = open('transactions.txt',"a")
   file.write("%16s%07d%16s\n" %(credit_card,price*100,description))
   file.close()

items = ["Sfiha","Coxinha","Pastel","Cheese bread"]
prices = [1.50,2.20,1.80,1.20]
running = True

while running:
   option = 1
   for item in items:
      print(str(option) + "." + item)
      option += 1
   print(str(option) + ".Finish")
   choice = int(input("Choose an option: "))
   if choice == option:
      #chose the last option
      running = False
   else:
      card = input("Credit card number: ")
      save_transaction(prices[choice-1],card,items[choice-1])

Products modified, but I forgot about the format!

   file.close()
