How do you construct an array suitable for numpy sorting? | 560,283 | <p>I need to sort two arrays simultaneously, or rather I need to sort one of the arrays and bring the corresponding element of its associated array with it as I sort.

Previously, you'd have had to write your own library to do so, using App Engine's urlfetch API, but with the release of SDK 1.1.9, you can now use urllib and httplib instead.</p>
