Python is een object-georiŽnteerde programmeertaal waarmee simpele tot complexe platformonafhankelijke applicaties kunnen worden ontwikkeld. De ontwikkelaars van deze programmeertaal hebben versie 3.0 uitgebracht. De 3.0-serie is niet meer backwards compatible met de voorgaande versietakken, omdat de Python-ontwikkelaars de taal wil opschonen van oude code en enkele aanwezige ontwerpfouten wil herstellen. De complete lijst met veranderingen voor Python 3.0 is op deze pagina na te lezen. De aankondiging van de 3.0-release ziet er als volgt uit:
On behalf of the Python development team and the Python community, I am happy to announce the release of Python 3.0 final.
Python 3.0 (a.k.a. "Python 3000" or "Py3k") represents a major milestone in Python's history, and was nearly three years in the making. This is a new version of the language that is incompatible with the 2.x line of releases, while remaining true to BDFL Guido van Rossum's vision. Some things you will notice include:
While these changes were made without concern for backward compatibility, Python 3.0 still remains very much "Pythonic".
- Fixes to many old language warts
- Removal of long deprecated features and redundant syntax
- Improvements in, and a reorganization of, the standard library
- Changes to the details of how built-in objects like strings and dicts work
- ...and many more new features
We are confident that Python 3.0 is of the same high quality as our previous releases, such as the recently announced Python 2.6. We will continue to support and develop both Python 3 and Python 2 for the foreseeable future, and you can safely choose either version (or both) to use in your projects. Which you choose depends on your own needs and the availability of third-party packages that you depend on. Some other things to consider:
We encourage you to participate in Python 3.0's development process by joining its mailing list. If you find things in Python 3.0 that are broken or incorrect, please submit bug reports. For more information, links to documentation, and downloadable distributions, see the Python 3.0 website.
- Python 3 has a single Unicode string type; there are no more 8-bit strings
- The C API has changed considerably in Python 3.0 and third-party extension modules you rely on may not yet be ported
- Tools are available in both Python 2.6 and 3.0 to help you migrate your code
- Python 2.6 is backward compatible with earlier Python 2.x releases
