title: Print pi to a number of decimal places
body: <p>One of the challenges on w3resources is to print pi to 'n' decimal places. Here is my code:</p>
  
  <pre><code>from math import pi
  
  fraser = str(pi)
  
  length_of_pi = []
  
  number_of_places = raw_input("Enter the number of decimal places you want to 
  see: ")
  
  for number_of_places in fraser:
      length_of_pi.append(str(number_of_places))
  
  print "".join(length_of_pi)
  </code></pre>
  
  <p>For whatever reason, it automatically prints pi without taking into account of any inputs. Any help would be great :)</p>
