  6  urlparse module is based upon the following RFC specifications.
  7  
  8  RFC 3986 (STD66): "Uniform Resource Identifiers" by T. Berners-Lee, R. Fielding
  9  and L.  Masinter, January 2005.
 10  
 11  RFC 2732 : "Format for Literal IPv6 Addresses in URL's by R.Hinden, B.Carpenter
 12  and L.Masinter, December 1999.
 13  
 14  RFC 2396:  "Uniform Resource Identifiers (URI)": Generic Syntax by T.
 15  Berners-Lee, R. Fielding, and L. Masinter, August 1998.
 16  
 17  RFC 2368: "The mailto URL scheme", by P.Hoffman , L Masinter, J. Zawinski, July 1998.
 18  
 19  RFC 1808: "Relative Uniform Resource Locators", by R. Fielding, UC Irvine, June
 20  1995.
 21  
 22  RFC 1738: "Uniform Resource Locators (URL)" by T. Berners-Lee, L. Masinter, M.
 23  McCahill, December 1994
 24  
 25  RFC 3986 is considered the current standard and any future changes to
 26  urlparse module should conform with it.  The urlparse module is
 27  currently not entirely compliant with this RFC due to defacto
 28  scenarios for parsing, and for backward compatibility purposes, some
 29  parsing quirks from older RFCs are retained. The testcases in
 30  test_urlparse.py provides a good indicator of parsing behavior.

 79  by reference to a primary resource and additional identifying information.

272  
273      Each part of a URL, e.g. the path info, the query, etc., has a
274      different set of reserved characters that must be quoted. The
275      quote function offers a cautious (not minimal) way to quote a
276      string for most of these parts.
277  
278      RFC 3986 Uniform Resource Identifier (URI): Generic Syntax lists
279      the following (un)reserved characters.
280  
281      unreserved    = ALPHA / DIGIT / "-" / "." / "_" / "~"
282      reserved      = gen-delims / sub-delims
283      gen-delims    = ":" / "/" / "?" / "#" / "[" / "]" / "@"
284      sub-delims    = "!" / "$" / "&" / "'" / "(" / ")"
285                    / "*" / "+" / "," / ";" / "="
286  
287      Each of the reserved characters is reserved in some component of a URL,
288      but not necessarily in all of them.
289  
290      The quote function %-escapes all characters that are neither in the
291      unreserved chars ("always safe") nor the additional chars set via the
292      safe arg.
293  
294      The default for the safe arg is '/'. The character is reserved, but in
295      typical usage the quote function is being called on a path where the
296      existing slash characters are to be preserved.
297  
298      Python 3.7 updates from using RFC 2396 to RFC 3986 to quote URL strings.
299      Now, "~" is included in the set of unreserved characters.
300  
301      string and safe may be either str or bytes objects. encoding and errors
302      must not be specified if string is a bytes object.
303  
304      The optional encoding and errors parameters specify how to deal with
305      non-ASCII characters, as accepted by the str.encode method.
306      By default, encoding='utf-8' (characters are encoded with UTF-8), and
307      errors='strict' (unsupported characters raise a UnicodeEncodeError).

346      If any values in the query arg are sequences and doseq is true, each

348  
349      If the query arg is a sequence of two-element tuples, the order of the
350      parameters in the output will match the order of parameters in the
