HISTORY OF THE SOFTWARE ========================== Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands as a successor of a language called ABC. Guido remains Python's principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see http://www.opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived Year Owner GPL- from compatible? (1) 0.9.0 thru 1.2 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Footnotes: (1) GPL-compatible doesn't mean that we're distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don't. (2) According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 is "not incompatible" with the GPL. Thanks to the many outside volunteers who have worked under Guido's direction to make these releases possible. B.

As the * example above shows, the add_argument() method is used to populate * the parser with actions for optional and positional arguments. Then * the parse_args() method is invoked to convert the args at the * command-line into an object with attributes. * * - ArgumentError -- The exception raised by ArgumentParser objects when * there are errors with the parser's actions. Errors raised while * parsing the command-line are caught by ArgumentParser and emitted * as command-line messages. * * - FileType -- A factory for defining types of files to be created. As the * example above shows, instances of FileType are typically passed as * the type= argument of add_argument() calls. * * - Action -- The base class for parser actions. Typically actions are * selected by passing strings like 'store_true' or 'append_const' to * the action= argument of add_argument(). However, for greater * customization of ArgumentParser actions, subclasses of Action may * be defined and passed as the action= argument. * * - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter, * ArgumentDefaultsHelpFormatter -- Formatter classes which * may be passed as the formatter_class= argument to the * ArgumentParser constructor. HelpFormatter is the default, * RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser * not to change the formatting for help text, and * ArgumentDefaultsHelpFormatter adds information about argument defaults * to the help. * * All other classes in this module are considered implementation details. * (Also note that HelpFormatter and RawDescriptionHelpFormatter are only * considered public as object names -- the API of the formatter objects is * still considered an implementation detail.) */ const SUPPRESS = '==SUPPRESS==' const OPTIONAL = '?' const ZERO_OR_MORE = '*' const ONE_OR_MORE = '+' const PARSER = 'A...' const REMAINDER = '...' const _UNRECOGNIZED_ARGS_ATTR = '_unrecognized_args' // ================================== // Utility functions used for porting // ================================== const assert = require('assert') const util = require('util') const fs = require('fs') const sub = require('./lib/sub') const path = require('path') const repr = util.inspect function get_argv() { // omit first argument (which is assumed to be interpreter - `node`, `coffee`, `ts-node`, etc.) return process.argv.slice(1) } function get_terminal_size() { return { columns: +process.env.COLUMNS || process.stdout.columns || 80 } } function hasattr(object, name) { return Object.prototype.hasOwnProperty.call(object, name) } function getattr(object, name, value) { return hasattr(object, name) ?
