Hi Rahul,


The language itself doesn't specify blocking/nonblocking IO features, but
there are several libraries that do.  For example, there's a library
module called asyncore:

    http://www.python.org/doc/lib/module-asyncore.html
    http://www.python.org/doc/lib/module-asynchat.html

that provides core support for asynchronous IO.


Not only is there good support from the Standard Library, but there are
also some nice third-party modules.  In particular, there's a
comprehensive package called "Twisted Python":

The Twisted folks are wrapping all kinds of network protocols with an
asynchronous IO interface, including ftp, telnet, http, instant messaging,
and a whole lot of other protocols... *grin*


Anyway, hope those links are helpful for you.  If you have more questions,
please feel free to ask.  Good luck!
