How can I handle the char immediately after its input, without waiting an endline?

I uses some of them a lot... less and top is on the top of my list (pun 
intended). I sometimes used vi(m), although I never really liked it, but 
it's sometimes unavoidable. info is replaced by man. lynx and links... 
well I remember a time when I tried to install Gentoo on a VMWare, lynx/
links (I forgot which one) was a life-saver because I wouldn't need to 
get out to the Windows host every two seconds to see the installation 
instruction (I was new to Linux at that time), and that was on a VMWare, 
what if I installed it directly, not on a virtual machine?

And as far as I know, it is impossible to implement a "press any key" 
feature with python in a simple way (as it should be). And if std input's 
character buffering is easy, it'd contribute a lot to command-line real 
time action games (and of course many other programs, but that is the 
first genre of programs that crosses my mind).
