title: Make python ask questions from strings
body: <p>I want to make python ask questions to the user - from random variables in lists. 
  It needs to ask the question requiring an input from the user.</p>
  
  <p>This is my code so far: </p>
  
  <pre><code>import time 
  import random 
  question = "0" 
  score = "0" 
  name = input("What is your full name?") 
  print ("Hello " + name, "welcome to The Arithmetic Quiz") 
  time.sleep(2) 
  numbers = list(range(1, 50)) 
  operators = ["+", "-", "*"] 
  numbers1 = list(range(1,10)) 
  print(str(random.choice(numbers)) + random.choice(operators) + str(random.choice(numbers1)))`
  </code></pre>
  
  <p>How would I make the last line of code ask a question and get an input from the user?</p>
  
  <p>Also how would I make it so that python says whether this is correct when I do not know what python will ask?</p>
