Questions tagged [python-3.6]

Version of the Python programming language released in December 2016. For issues specific to Python 3.6. Use more generic [python] and [python-3.x] tags where possible.

Python 3.6 is the currently newest version of the popular Python programming language (see PEP 0494).

Use this tag if your question is specifically related to Python 3.6. Otherwise, use the following guidelines to determine which tag(s) you should add to your question:

  • If your question applies to Python in general, use only the tag.
  • If your question applies to Python 3.x but not to Python 2.x, add the tag .
  • If you aren't sure, tag your question with and mention which version you're using in the post.
