13. Parsing response
code as dictionary

14. Threads supported

15. Can I replace other languages
by python?

16. Real example of usage
› A script to update subscriber

› Seeking information into 3.5 M
subscribers database
› Comparing account expiration
dates
› Updating accordingly required
accounts
› Using XML-rpc for updating
› Started in Perl, but perlcc
crashed
› Moved to Python, compiled with

17. Perl code

18. Python code

19. Python everywhere
