suggestions on using Python to connect to Web servers (e.g. to access
financial time series data)?

You can open a web page for reading with urllib2 module. You can parse
html with beautiful soup, or if it's clean xhtml, with the xml module.
But parsing raw html is error prone, and subject to change as the web
designer reorganizes things. So many web servers also have a protocol
intended for data (as opposed to intended for a browser). This is
specific to each service, however. If you want to get started in your
reading, you could google for web services, which is one approach
using SOAP WSDL.
Note also that most servers have restrictions on the data you access
this way. They may or may not be enforceable, but if you access a lot
of data from a server, you may be too big a drain on its resources, if
it's configured for browser access only.
