title: Python program, how to make an atm program loop
body: <p>How do i make it loop back to the start after doing this? After each transaction, it ends and doesn't go back to see if you can pick another option.
  Thanks and it's greatly appreciated.   </p>
  
  <pre><code>balance=7.52
  print("Hi, Welcome to the Atm.")
  print("no need for pin numbers, we already know who you are")
  print("please selection one of the options given beneath")
  print("""
      D = Deposit
      W = Withdrawal
      T = Transfer
      B = Balance check
      Q = Quick cash of 20$
      E = Exit
      Please select in the next line.   
  """)
  option=input("which option would you like?:")
  if option==("D"):
      print("How much would you like to deposit?")
      amount=(int(input("amount:")))
      total=amount+balance
  elif option ==("W"):
      print("How much would you like to withdrawl?")
      withdrawl=int(input("how much would you like to take out:?"))
      if balance&lt;withdrawl:
          print("Error, insufficent funds")
          print("please try again")
  elif option == "T":
      print("don't worry about the technicalities, we already know who you're          transferring to")
      transfer =int(input("How much would you like to transfer:?"))
      print("you now have", balance-transfer,"dollars in your bank")
  elif option=="B":
      print("you currently have",balance,"dollars.")
  elif option=="Q":
      print("processing transaction, please await approval")
      quicky=balance-20
      if balance&lt;quicky:
           print("processing transaction, please await approval")
      print("Error, You're broke.:(")
  elif option=="E":
        print("Thanks for checking with the Atm")
        print("press the enter key to exit")
