Python program to calculate harmonic series

Question

Does anyone know how to write a program in Python that will calculate the addition of the harmonic series. i.e. 1 + 1/2 +1/3 +1/4...

Answer 1

Homework?

It's a divergent series, so it's impossible to sum it for all terms.

I don't know Python, but I know how to write it in Java.

public class Harmonic
{
    private static final int DEFAULT_NUM_TERMS = 10;

    public static void main(String[] args)
    {
        int numTerms = ((args.length > 0) ? Integer.parseInt(args[0]) : DEFAULT_NUM_TERMS);

        System.out.println("sum of " + numTerms + " terms=" + sum(numTerms));
     }

     public static double sum(int numTerms)
     {
         double sum = 0.0;

         if (numTerms > 0)
         {
             for (int k = 1; k <= numTerms; ++k)
             {
                 sum += 1.0/k;
             }
         }

         return sum;
     }
 }
