You can use the tool designed for the job:

   bash$ paste file1.txt file2.txt

Or, if you want to use Python you might be interested in

   for a,b in zip(file('file1.txt'), file('file2.txt')):
     print '%s\t%s' % (a.strip(), b.strip())

If they're big, import itertools.izip() and use it instead of zip()

Variants may be needed depending on the behavior if file1 and 
file2 have different numbers of lines in them.
