Change emacs org-mode key binding for code block

Question

In org-mode I use <s then TAB to insert a code block. This action will insert a code block like

 #+BEGIN_SRC
    .
    .
    .
 #+END_SRC

but I want to modify this action to insert something like

#+BEGIN_SRC python -n :results output pp replace :exports both
    .
    .
    .
#+END_SRC

I know it's possible to change default behaviour of :result or :exports in emacs init file but I prefer to change this shortcut behaviour, because it makes me able to change the options in line.

Answering my own question based on legoscia's answer.

As mentioned in the Easy Templates section of the org-mode manual, you can modify these templates by customizing the variable org-structure-template-alist. Using M-x customize-option and applying changes will add all easy templates to your init file, if you don't like it you can add just one line to your init file to change a template or add one.

In my case I added this line to my emacs init file to add <p then TAB :

(add-to-list 'org-structure-template-alist '("p" "#+BEGIN_SRC python -n :results output pp replace :exports both\n?\n#+END_SRC"))
