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] = '_'
which would result in word printing 'c_t'.
That's simply not true in Python. Try it out!
>>> word = "cat"
>>> word[1] = "_"
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
word[1] = "_"
TypeError: 'str' object does not support item assignment
>>>

I'm assuming your use case would be just a call to random with bounds
zero -> length of string - 1 and then using that index to replace the
character with an underscore and it is much simpler and faster to just
use the strings build in index and item assignment.
Hope that helps.
