urlparse module is based upon the following RFC specifications.
RFC 3986 (STD66): "Uniform Resource Identifiers" by T. Berners-Lee, R. Fielding
and L. Masinter, January 2005.
RFC 2732 : "Format for Literal IPv6 Addresses in URL's by R.Hinden, B.Carpenter
and L.Masinter, December 1999.
RFC 2396: "Uniform Resource Identifiers (URI)": Generic Syntax by T.
Berners-Lee, R. Fielding, and L. Masinter, August 1998.
RFC 2368: "The mailto URL scheme", by P.Hoffman , L Masinter, J. Zawinski, July 1998.
RFC 1808: "Relative Uniform Resource Locators", by R. Fielding, UC Irvine, June
1995.
RFC 1738: "Uniform Resource Locators (URL)" by T. Berners-Lee, L. Masinter, M.
McCahill, December 1994
RFC 3986 is considered the current standard and any future changes to
urlparse module should conform with it. The urlparse module is
currently not entirely compliant with this RFC due to defacto
scenarios for parsing, and for backward compatibility purposes, some
parsing quirks from older RFCs are retained. The testcases in
test_urlparse.py provides a good indicator of parsing behavior.
The WHATWG URL Parser spec should also be considered. We are not compliant with
it either due to existing user code API behavior expectations (Hyrum's Law).
It serves as a useful guide when making changes.

DefragResult(url, fragment)
A 2-tuple that contains the url without fragment identifier and the fragment
identifier as a separate argument.
z$The URL with no fragment identifier.z
Fragment identifier separated from URL, that allows indirect identification of a
secondary resource by reference to a primary resource and additional identifying
information.
z
SplitResult(scheme, netloc, path, query, fragment)
A 5-tuple that contains the different components of a URL. Similar to
ParseResult, but does not split params.
z%Specifies URL scheme for the request.z0
Network location where the request is made to.
z@
The hierarchical path, such as the path to a file to download.
z
The query component, that contains non-hierarchical data, that along with data
in path component, identifies a resource in the scope of URI's scheme and
network location.
z
Fragment identifier, that allows indirect identification of a secondary resource
by reference to a primary resource and additional identifying information.
zr
ParseResult(scheme, netloc, path, params, query, fragment)
A 6-tuple that contains components of a parsed URL.
z
Parameters for last path element used to dereference the URI in order to provide
access to perform some operation on the resource.

Each part of a URL, e.g. the path info, the query, etc., has a
different set of reserved characters that must be quoted.
RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax lists
the following reserved characters.
reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" |
"$" | ","
Each of these characters is reserved in some component of a URL,
but not necessarily in all of them.
By default, the quote function is intended for quoting the path
section of a URL. Thus, it will not encode '/'. This character
is reserved, but in typical usage the quote function is being
called on a path where the existing slash characters are used as
reserved characters.
string and safe may be either str or bytes objects. encoding and errors
must not be specified if string is a bytes object.
The optional encoding and errors parameters specify how to deal with
non-ASCII characters, as accepted by the str.encode method.
By default, encoding='utf-8' (characters are encoded with UTF-8), and
errors='strict' (unsupported characters raise a UnicodeEncodeError).
