I tried with this:

print columns[0], columns[1]

If your files have two blank lines between each useful line, you have to
do something to avoid trying to print those items for the blank lines.
Depending how sure you are about your formatting, you could either do a
if not line: continue
or a
if columns < 3: continue

(Don't top-post. It makes the message very confusing to someone else
trying to follow it. Also, enable your mail program's quoting feature
-- currently it's not adding the marks at the beginning of each line
you quote.)
If you're going to skip over blank lines, it'd be good to do it before
trying to print from it. Move the test up by a line.

for line in open('1.txt'):
columns = line.split()
if len(columns) < 2:
continue #skip over lines that
don't have at least 2 columns
print columns[0], columns[1]
