Everything about Cpython totally explained
CPython is the default, most-widely used implementation of the
Python programming language. It is written in
C. In addition to CPython, there are two other production-quality Python implementations:
Jython, written in
Java, and
IronPython, which is written for the
Common Language Runtime, as well as several experimental implementations. The
backronym Classic Python has been suggested as another meaning for the 'C'.
CPython is a
bytecode interpreter. It has a
foreign function interface with several languages including C, in which one must explicitly write
bindings in a language other than Python.
Supported platforms
Previously supported platforms
PEP 11
lists platforms which are not supported in CPython by
Python Software Foundation. These platforms can still be supported by external ports. See below.
DOS (unsupported since 2.0)
IRIX 4 (unsupported since 2.3)
Mac OS 9 (unsupported since 2.4)
Minix (unsupported since 2.3)
External ports
These are ports not integrated to Python Software Foundation's official version of CPython, with links to its main development site. Ports often include additional modules for platform-specific functionalities, like graphics and sound API for PSP and SMS and camera API for S60.
Amiga (External Link)
AS/400 (External Link)
DOS using DJGPP (External Link)
PlayStation Portable (External Link)
Symbian OS (External Link)
Windows CE/Pocket PC (External Link)
Concurrency Issues
The main issue of using CPython on a multiprocessor computer is the presence of a Global Interpreter Lock on each CPython interpreter process, which effectively disables concurrent Python threads within one process. To be truly concurrent in multiprocessor environment, separate CPython interpreter processes have to be run, which makes establishing communication between them a difficult task. There is constant discussion whether to remove the GIL from CPython.

External Link Exchanges
Do you know how hard it is to get a link from a large encyclopaedia? Well we're different and will prove it. To get a link from us just add the following HTML to your site on a relevant page:
<a href="http://cpython.totallyexplained.com">CPython Totally Explained</a>
Then simply click through this link from your web page. Our crawlers will verify your link, extract the title of your web page and instantly add a link back to it. If you like you can remove the words Totally Explained and embed the link in article text.
As long as your link remains in place, we'll keep our link to you right here. Please play fair - our crawlers are watching. Your site must be closely related to this one's topic. Any kind of spamming, dubious practises or removing the link will result in your link from us being dropped and, potentially, your whole site being banned. |
