title: fixed point iteration algorithm
body: <p>I am asked to write a program to solve this equation ( x^3 + x -1 = 0 ) using fixed point iteration.</p>
  
  <p>What is the algorithm for fixed point iteration? 
  Is there any fixed point iteration code sample in Python? (not a function from any modules, but the code with algorithms)</p>
  
  <p>Thank You</p>
