How can I find the sum of a series of integers with powers eg, n^(n 1)?

edit

This looks like homework. Here are some hints:

• to create the list of the terms, search for list comprehension,
• to get only odd numbers, note that the range function has a step option, so that you can jump 2 by 2,
• then use the sum function to sum all elements of the list you obtained.

The result should start with 149 and end with 478.
