Equivalent of C++ for loop in python : What will be the python equivalent to this simple C++ code :

    for (i = 0; i < 10; i++)
      {
        for (j = 10; j > i; j--)
         {  
           a[i]*a[j];
         }
      }
Especially I am having problem in the implementation of the second loop with 'j' using the 
  

      j > i

condition
