There might be a different way, but here is one that I can think of:
{% set letters = cycler(*'abcdefghijklmnopqrstuvwxyz'[:]) %}
slave_hosts={% for host in slaves %}{{ letters.next() }}:{{ host }}{% if
not loop.last %},{% endif %}{% endfor %}
This creates a 'cycler' with the lowercase letters of the english alphabet,
and cycles through them on each iteration of the for loop.
