beginer question of list comprehensions

[Echo]

Ok, this is the first list comprehension that I have done.
Surprisinly, it works for the most part.
The problem with it is that it returns a list with two lists in it,
instead of just one list. Can anyone tell me what I am doing wrong or
how to fix it.

Here is my code:
[t for t in (__import__(m, globals(), locals(), m).BizObjects() for m
in table_files)]

"table_files" is a list with two module names
"__import__(m, globals(), locals(), m).BizObjects()" is a list of
objects gotten from the module.
