batch mkdir using a file list

[DataSmash]

Hello,
I think I've tried everything now and can't figure out how to do it.
I want to read in a text list from the current directory,
and for each line in the list, make a system directory for that name.

My text file would look something like this:
1144
1145
1146
1147

I simply want to create these 4 directories.
It seems like something like the following
code should work, but it doesn't.

import os

file = open("list.txt", "r")
read = file.read()
print "Creating directory " + str(read)
os.mkdir(str(read))

Appreciate any help you can give!
