Yes, that's a feature. Otherwise you'll open yourself up to a variety
of attacks:

If you want to turn off that defense, set "UseEntryGuards 0" in your
torrc.

Or you can delete them from your $datadir/state file while Tor is off,
but that's probably more likely to cause problems.

You can get it from SVN:
https://svn.torproject.org/svn/torctl/trunk/python/

Playing around and testing with telnet or nc is a fine start. You only
need the torctl library if you find that playing around by hand is
insufficient for your needs.
