• The server sets up an environment containing variables which indicate various aspects of the request.
  
• 
  The server invokes the CGI program in that environment.
  
• 
  The server passes the request body (if any) to the program on standard input.
  
• 
  The program uses the CGI environment variables and the standard input (if any) to figure out what to do.
  
• 
  The program spits the status line and headers to standard output, followed by a separator, followed by the response body.
  
• 
  The server reads this and turns it into an HTTP response back to the client.

__init__.py file and put some stuff in there.

import doctst
__test__ = {
    'Doctest': doctst
}

To decode a string, use the decode() method on the input
string, and pass it the name of the encoding:

    fileencoding = "iso-8859-1"

    raw = file.readline()
    txt = raw.decode(fileencoding)

(the result is a Python Unicode string).

The decode method was added in Python 2.2. In earlier
versions (or if you think it reads better), use the unicode
constructor instead:

   txt = unicode(raw, fileencoding)

To create a regular expression pattern that uses Unicode character
classes for \w (and \s, and \b), use the “(?u)” flag prefix, or
the re.UNICODE flag:

    pattern = re.compile("(?u)pattern")

    pattern = re.compile("pattern", re.UNICODE)

To write a Unicode string to a file or other device, you have to
convert it to the encoding used by the file. The encode method
converts from Unicode to an encoded string.

    out = txt.encode(encoding)

If the string contains characters that cannot be represented in the
given encoding, Python raises an exception. You can change this by
passing in a second argument to encode:

    # skip bad chars
    out = txt.encode(encoding, "ignore")

    # replace bad chars with "?"
    out = txt.encode(encoding, "replace")

    import locale
    language, output_encoding = locale.getdefaultlocale()

    print txt.encode(output_encoding)

Convert a byte string into a Unicode string and back again:

s = "hello byte string"
u = unicode( s )
backToBytes = u.encode()
