Strings are essentially a list already of characters. What would
be slowing down your preferred method #1 would be your explicit
cast to a list and then re-joining that list. Strings support
item assignment so you can save quite a few cycles just doing
word = 'cat'
word[1] = '_'
Not in python they don't!
In [97]: word[1]='_'

TypeError: 'str' object does not support item assignment
But of course I already knew that from experience :-P

Whoops, early morning, lack of coffee, some deadlines on my head to
blame for that. :p
Rebuilding strings would be faster using concatenation than casting to
list and joining, it is the method I prefer when cutting things out. I
also find it looks neater and is easier to read. Also '%s%s%s' %
(a[:idx], '_', a[idx+1:]) would be preferred over a[:idx] + '_' + a[idx+1:]
