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.
