You don't need a loop:

items = ['a', 'b', 'c', 'd']
result = "".join(items)

Note that it's a bad idea to use list as the name of a variable, because that prevents you from using list to mean the built-in type.

Is this what you are looking for?

>>> my_list = ['a', 'b', 'c', 'd']
>>> "".join(my_list)
'abcd'

You shouldn't use list as a variable name, since this will shadow the built-in class list.

@DanielPryden: This happened to me even within the same second. It is a bit more surprising for this post, though, since the "question" isn't the clearest one ever posted on SO. (+1 for you.)
