Questions tagged [python-3.2]

For issues that are specific to Python 3.2. Use the more generic [python] and [python-3.x] tags where possible.

Although Python 3 itself is ready for primetime and stable, many of the popular libraries have not yet been ported.

See also Python2 or Python3.

Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only.

It has been superseded by Python 3.3.

Tagging recommendation:

Use the tag for all Python related questions. If you believe your question includes issues specific to the incompatible Python 2.x or Python 3.x, in addition to the main tag, use or . If you believe your question may be even more specific, you can include a version specific tag such as .
