Thanks for that.  Very illuminating and interesting.  I hadn't come across 
that command before.  (I tend to look things up in man aptitude rather than 
read it through.)

But in my case it only served to illustrate that nothing of any real 
importance in my system depends on Python.  In fact, not only were there no 
direct dependency chains leading to Python, since all of them had at least 
2 "suggests" in the chain, the few things that did depend on Python, at the 
end of the chain, after the suggests, were mostly not installed, so would not 
have missed Python.
