How to care for an URI and feed it?

I am developing an application, which needs to be aware of the concept of URI. A quick Google search yielded the following URLs:

  1. What’s a URI?
  2. MonkeyX’s Hairy Thoughts about semantic Webs

What I really would like to:

  1. Find how to specify a section inside a file, in terms of offset relative to beginning and length.
  2. Locate a Python module, which knows to do everything a mortal needs to do with URIs.

I am deaf since birth. I played with big computers which eat punched cards and spew out printouts since age 12. Ever since they became available, I work and play with desktop size computers which eat keyboard keypresses and spew out display pixels. Among other things, I developed software which helped the deaf in Israel use the telephone network, by means of home computers equipped with modems. Several years later, I developed Hebrew localizations for some cellular phones, which helped the deaf in Israel utilize the cellular phone networks. I am interested in entrepreneurship, Science Fiction and making the world more accessible to people with disabilities.
