In python 2 7  the   operator is integer division if inputs are integers   If you want float division  which is something I always prefer   just use this special import   from   future   import division   See it here    gt  gt  gt  7   2 3  gt  gt  gt  from   future   import division  gt  gt  gt  7   2 3 5  gt  gt  gt    Integer division is achieved by using     and modulo by using     gt  gt  gt  7   2 1  gt  gt  gt  7    2 3  gt  gt  gt    EDIT  As commented by user2357112  this import has to be done before any other normal import
