title: Python3 My Code Doesn't want input again
body: <pre><code>asd = 1
  limit = "+-*/1234567890 "
  
  while asd:
      data = input("YOUR PROCESS? ")
      for i in data:
  
          if i not in limit:
              print("?? ERROR ?? ")
              quit()
  
          else:
              print(eval(data))
  
              again = input("AGAIN? (E/H)")
  
              if again == "E":
                  pass
  
              else:
                   print("GOOD BYE... \n")
                   asd = 0
  </code></pre>
  
  <p>When I execute this code after one process, it doesn't want new value for "data". Running with first data value. How can i solve this? </p>
