Python and productivity

Python increases productivity unimaginable. Even though you've never had written any code with it, you can understand its very nice syntax. Consider this:

def fibonacci(n) :
   if n==0 or n==1 :
      return 1
   else :
      return fibonacci(n-1) + fibonacci(n-2)

Like common speaking huh? seems pseudo code ! Now imagine you have decided to implement an algorithm (a very hard and comprehensive one) with python. Believe me,It takes 30 min in max :)
