<h2>History of the software<a class="headerlink" href="#history-of-the-software" title="Link to this heading">¶</a></h2>
|
||
<p>Python was created in the early 1990s by Guido van Rossum at Stichting
|
||
Mathematisch Centrum (CWI, see <a class="reference external" href="https://www.cwi.nl">https://www.cwi.nl</a>) in the Netherlands as a
|
||
successor of a language called ABC. Guido remains Python’s principal author,
|
||
although it includes many contributions from others.</p>
|
||
<p>In 1995, Guido continued his work on Python at the Corporation for National
|
||
Research Initiatives (CNRI, see <a class="reference external" href="https://www.cnri.reston.va.us">https://www.cnri.reston.va.us</a>) in Reston,
|
||
Virginia where he released several versions of the software.</p>
|
||
<p>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
|
||
<a class="reference external" href="https://www.python.org/psf/">https://www.python.org/psf/</a>) was formed, a non-profit organization created
|
||
specifically to own Python-related Intellectual Property. Zope Corporation was a
|
||
sponsoring member of the PSF.</p>
|
||
<p>All Python releases are Open Source (see <a class="reference external" href="https://opensource.org">https://opensource.org</a> for the Open
|
||
Source Definition). Historically, most, but not all, Python releases have also
|
||
been GPL-compatible; the table below summarizes the various releases.</p>

- Use binascii module to do the actual line-by-line conversion

between ascii and binary. This results in a 1000-fold speedup. The C

version is still 5 times faster, though.

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||
|
||
1. Definitions.
|
||
|
||
"License" shall mean the terms and conditions for use, reproduction,
|
||
and distribution as defined by Sections 1 through 9 of this document.
|
||
|
||
"Licensor" shall mean the copyright owner or entity authorized by
|
||
the copyright owner that is granting the License.
|
||
|
||
"Legal Entity" shall mean the union of the acting entity and all
|
||
other entities that control, are controlled by, or are under common
|
||
control with that entity. For the purposes of this definition,
|
||
"control" means (i) the power, direct or indirect, to cause the
|
||
direction or management of such entity, whether by contract or
|
||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||
|
||
"You" (or "Your") shall mean an individual or Legal Entity
|
||
exercising permissions granted by this License.
|
||
|
||
"Source" form shall mean the preferred form for making modifications,
|
||
including but not limited to software source code, documentation
|
||
source, and configuration files.
|
||
|
||
"Object" form shall mean any form resulting from mechanical
|
||
transformation or translation of a Source form, including but
|
||
not limited to compiled object code, generated documentation,
|
||
and conversions to other media types.
|
||
|
||
"Work" shall mean the work of authorship, whether in Source or
|
||
Object form, made available under the License, as indicated by a
|
||
copyright notice that is included in or attached to the work
|
||
(an example is provided in the Appendix below).
|
||
|
||
"Derivative Works" shall mean any work, whether in Source or Object
|
||
form, that is based on (or derived from) the Work and for which the
|
||
editorial revisions, annotations, elaborations, or other modifications
|
||
represent, as a whole, an original work of authorship. For the purposes
|
||
of this License, Derivative Works shall not include works that remain
|
||
separable from, or merely link (or bind by name) to the interfaces of,
|
||
the Work and Derivative Works thereof.
|
||
|
||
"Contribution" shall mean any work of authorship, including
|
||
the original version of the Work and any modifications or additions
|
||
to that Work or Derivative Works thereof, that is intentionally
|
||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||
or by an individual or Legal Entity authorized to submit on behalf of
|
||
the copyright owner. For the purposes of this definition, "submitted"
|
||
means any form of electronic, verbal, or written communication sent
|
||
to the Licensor or its representatives, including but not limited to
|
||
communication on electronic mailing lists, source code control systems,
|
||
and issue tracking systems that are managed by, or on behalf of, the
|
||
Licensor for the purpose of discussing and improving the Work, but
|
||
excluding communication that is conspicuously marked or otherwise
|
||
designated in writing by the copyright owner as "Not a Contribution."
|
||
|
||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||
on behalf of whom a Contribution has been received by Licensor and
|
||
subsequently incorporated within the Work.
|
||
|
||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||
this License, each Contributor hereby grants to You a perpetual,
|
||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||
copyright license to reproduce, prepare Derivative Works of,
|
||
publicly display, publicly perform, sublicense, and distribute the
|
||
Work and such Derivative Works in Source or Object form.
|
||
|
||
3. Grant of Patent License. Subject to the terms and conditions of
|
||
this License, each Contributor hereby grants to You a perpetual,
|
||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||
(except as stated in this section) patent license to make, have made,
|
||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||
where such license applies only to those patent claims licensable
|
||
by such Contributor that are necessarily infringed by their
|
||
Contribution(s) alone or by combination of their Contribution(s)
|
||
with the Work to which such Contribution(s) was submitted. If You
|
||
institute patent litigation against any entity (including a
|
||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||
or a Contribution incorporated within the Work constitutes direct
|
||
or contributory patent infringement, then any patent licenses
|
||
granted to You under this License for that Work shall terminate
|
||
as of the date such litigation is filed.
|
||
|
||
4. Redistribution. You may reproduce and distribute copies of the
|
||
Work or Derivative Works thereof in any medium, with or without
|
||
modifications, and in Source or Object form, provided that You
|
||
meet the following conditions:
|
||
|
||
(a) You must give any other recipients of the Work or
|
||
Derivative Works a copy of this License; and
|
||
|
||
(b) You must cause any modified files to carry prominent notices
|
||
stating that You changed the files; and
|
||
|
||
(c) You must retain, in the Source form of any Derivative Works
|
||
that You distribute, all copyright, patent, trademark, and
|
||
attribution notices from the Source form of the Work,
|
||
excluding those notices that do not pertain to any part of
|
||
the Derivative Works; and
|
||
|
||
(d) If the Work includes a "NOTICE" text file as part of its
|
||
distribution, then any Derivative Works that You distribute must
|
||
include a readable copy of the attribution notices contained
|
||
within such NOTICE file, excluding those notices that do not
|
||
pertain to any part of the Derivative Works, in at least one
|
||
of the following places: within a NOTICE text file distributed
|
||
as part of the Derivative Works; within the Source form or
|
||
documentation, if provided along with the Derivative Works; or,
|
||
within a display generated by the Derivative Works, if and
|
||
wherever such third-party notices normally appear. The contents
|
||
of the NOTICE file are for informational purposes only and
|
||
do not modify the License. You may add Your own attribution
|
||
notices within Derivative Works that You distribute, alongside
|
||
or as an addendum to the NOTICE text from the Work, provided
|
||
that such additional attribution notices cannot be construed
|
||
as modifying the License.
|
||
|
||
You may add Your own copyright statement to Your modifications and
|
||
may provide additional or different license terms and conditions
|
||
for use, reproduction, or distribution of Your modifications, or
|
||
for any such Derivative Works as a whole, provided Your use,
|
||
reproduction, and distribution of the Work otherwise complies with
|
||
the conditions stated in this License.
|
||
|
||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||
any Contribution intentionally submitted for inclusion in the Work
|
||
by You to the Licensor shall be under the terms and conditions of
|
||
this License, without any additional terms or conditions.
|
||
Notwithstanding the above, nothing herein shall supersede or modify
|
||
the terms of any separate license agreement you may have executed
|
||
with Licensor regarding such Contributions.
|
||
|
||
6. Trademarks. This License does not grant permission to use the trade
|
||
names, trademarks, service marks, or product names of the Licensor,
|
||
except as required for reasonable and customary use in describing the
|
||
origin of the Work and reproducing the content of the NOTICE file.
|
||
|
||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||
agreed to in writing, Licensor provides the Work (and each
|
||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||
implied, including, without limitation, any warranties or conditions
|
||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||
appropriateness of using or redistributing the Work and assume any
|
||
risks associated with Your exercise of permissions under this License.
|
||
|
||
8. Limitation of Liability. In no event and under no legal theory,
|
||
whether in tort (including negligence), contract, or otherwise,
|
||
unless required by applicable law (such as deliberate and grossly
|
||
negligent acts) or agreed to in writing, shall any Contributor be
|
||
liable to You for damages, including any direct, indirect, special,
|
||
incidental, or consequential damages of any character arising as a
|
||
result of this License or out of the use or inability to use the
|
||
Work (including but not limited to damages for loss of goodwill,
|
||
work stoppage, computer failure or malfunction, or any and all
|
||
other commercial damages or losses), even if such Contributor
|
||
has been advised of the possibility of such damages.
|
||
|
||
9. Accepting Warranty or Additional Liability. While redistributing
|
||
the Work or Derivative Works thereof, You may choose to offer,
|
||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||
or other liability obligations and/or rights consistent with this
|
||
License. However, in accepting such obligations, You may act only
|
||
on Your own behalf and on Your sole responsibility, not on behalf
|
||
of any other Contributor, and only if You agree to indemnify,
|
||
defend, and hold each Contributor harmless for any liability
|
||
incurred by, or claims asserted against, such Contributor by reason
|
||
of your accepting any such warranty or additional liability.
