title: Python turtle user input
body: <p>I am trying to write some code that when the user inputs a shape the turtle draws it, this is what I have so far but it just draws a pentagon all the time</p>
  
  <pre><code>    import turtle
  turtle.shape('turtle')
  
  def triangle():
      for i in range(3):
          turtle.forward(50)
          turtle.right(360/3)
  
  
  def square():
      for i in range(4):
          turtle.forward(50)
          turtle.right(360/4)
  
  def pentagon():
      for i in range(5):
          turtle.forward(50)
          turtle.right(360/5)
  
  
  answer = input('pick a shape.. triangle, square or pentagon')
  if answer ==('triangle'):
      triangle()
  
  elif answer == ('square'):
      square()
  
  elif answer == ('pentagon'):
      pentagon()
  
  else:
      print ('wrong input')
  </code></pre>
