Python equivalents of the common Perl modules?

Question

I need to rewrite some Perl code in python. So I'm looking for the closest modules to what I'm using now in Perl (i.e. with similar functionality and stability):

• DBI + DBD::mysql
• LWP::UserAgent
• WWW::Mechanize
• XML::LibXML
• HTML::TreeBuilder
• CGI::FormBuilder
• Template::Toolkit

What are the Python equivalents to these?

Answer 1

• All Python database modules use the same API, so either MySQLdb or oursql will work.
• urllib2
• mechanize
• etree or lxml
• No direct equivalent, but BeautifulSoup and lxml can parse, and etree and lxml can generate.
• FormEncode
• Genshi, Jinja2, mako, cheetah, and too many others

urllib2 and etree are in the standard library; the rest are easy enough to get.
