(Sorry, forgot to reply to the list, too.)


I also can't tell you how those strings appear, but you can easily
work around it; you can do something like the following, for example.
If replace() or sub() don't find a match (when no other users are
logged in), the string remains unchanged.

---------- 8< ----------
import re

foo = run('some command')
print('debug #1: %s' % foo)

foo = foo.replace('Other users are logged in\n','')
print('debug #2: %s' % foo)

foo = 
re.sub(r'[a-z]+\s+pts/\d+\s+\d{4}-\d{1,2}-\d{1,2}\s+\d{1,2}:\d{2}\s+\(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\)\n','',foo)
print('debug #3: %s' % foo)
---------- >8 ----------

The regex is a bit coarse (as are my python skills), but it should work.
