title: Basic Python Algorithm Stress Test
body: <p>Hi I am learning the basics of algorithms using python, this is my first stress testing script (I am still new to python).</p>
  
  <p>When i run the test both the variables fast and result are printed as 0, the random number generator i included doesn't seem to be creating numbers for the functions mpp and mppf to use, either that or they are not assigning their results to the relevant variable, hence the variable remains = 0 and the loop keeps printing '0 0 OK'</p>
  
  <p>I am receiving no errors except for the fact that my script isn't doing what i want it too!</p>
