If you are working on Python it is very possible you will come across an issue where you need some assistance to solve it (this happens to core developers all the time).
Should you require help, there are a variety of options available to seek assistance. If the question involves process or tool usage then please check the rest of this guide first (especially the Python Developer FAQ) as it should answer your question.
If you are comfortable with IRC you can try asking on #python-dev (on the freenode network). Typically there are a number of experienced developers, ranging from triagers to core developers, who can answer questions about developing for Python. Just remember that #python-dev is for questions involving the development of Python whereas #python is for questions concerning development with Python.
If you are interested in improving Python and contributing to its development, but don’t yet feel entirely comfortable with the public channels mentioned above, Python Mentors are here to help you. Python is fortunate to have a community of volunteer core developers willing to mentor anyone wishing to contribute code, work on bug fixes or improve documentation. Everyone is welcomed and encouraged to contribute.
Further options for seeking assistance include the python-ideas and python-dev mailing lists. Python-ideas contains discussion of speculative Python language ideas for possible inclusion into the language. If an idea gains traction it can then be discussed and honed to the point of becoming a solid proposal and presented on python-dev. Python-dev contains discussion of current Python design issues, release mechanics, and maintenance of existing releases. As with #python-dev, these mailing lists are for questions involving the development of Python, not for development with Python.
If you strongly suspect you have stumbled on a bug (be it in the build process, in the test suite, or in other areas), then open an issue on the issue tracker. As with every bug report it is strongly advised that you detail which conditions triggered it (including the OS name and version, and what you were trying to do), as well as the exact error message you encountered.
