Using String for new List name

I am new to Python but I have studied hard and written a fairly big
(to me) script/program. I have solved all of my problems by Googling
but this one has got me stumped.

I want to check a string for a substring and if it exists I want to
create a new, empty list using that substring as the name of the list.
For example:

Let's say file1 has line1 through line100 as the first word in each

for X in open("file1"):
    Do a test.
    If true:
        Y = re.split(" ", X)
        Z = Y[0]          # This is a string, maybe it is "Line42"
        Z = []              # This doesn't work, I want a new, empty
list created called Line42 not Z.

Is there any way to do this?
