We welcome your contributions to Python! Here are the basic steps needed to get set up and contribute a patch. This is meant as a checklist, once you know the basics. For complete instructions please see the setup guide.

Install and set up Git and other dependencies see the Git Setup page for detailed information. Fork the CPython repository to your GitHub account and get the source code using:. Run the tests :. On most Mac OS X systems, replace. On Windows, use python. With Python 2. If an issue does not already exist, please create it. Trivial issues e. Once you fixed the issue, run the tests, run make patchcheckand if everything is ok, commit.

Push the branch on your fork on GitHub and create a pull request. Include the issue number using bpo-NNNN in the pull request description. For example:. The master branch is currently the future Python 3. The latest release for each Python version can be found on the download page. By default, the end-of-life is scheduled 5 years after the first release, but can be adjusted by the release manager of each branch.

All Python 2 versions have reached end-of-life.

See also the Development Cycle page for more information about branches. If you still have questions after reviewing the material in this guide, then the Core Python Mentorship group is available to help guide new contributors through the process. A number of individuals from the Python community have contributed to a series of excellent guides at Open Source Guides.

It is recommended that the above documents be read as needed. New contributors will build understanding of the CPython workflow by reading the sections mentioned in this table. You can stop where you feel comfortable and begin contributing immediately without reading and understanding these documents all at once.

If you do choose to skip around within the documentation, be aware that it is written assuming preceding documentation has been read so you may find it necessary to backtrack to fill in missing concepts and terminology. While these kinds of change are much rarer than those described above, they do happen and that process is also described as part of this guide:. There are other Python implementations, each with a different focus.

Like CPython, they always have more things they would like to do than they have developers to work on them. Some major examples that may be of interest are:.

You must also work well with other core developers and people in general as you become an ambassador for the Python project. Typically a core developer will offer you the chance to gain commit privilege. The person making the offer will become your mentor and watch your commits for a while to make sure you understand the development process.

If other core developers agree that you should gain commit privileges you are then extended an official offer. How core developers come to that agreement are outlined in PEP As contributors to the CPython project, our shared responsibility is to collaborate constructively with other contributors, including core developers. Core developers accept key additional responsibilities around the ongoing management of the project:. As a result of the additional responsibilities they accept, core developers gain the privilege of being able to approve proposed changes, as well as being able to reject them as inappropriate.

Core developers are also able to request that even already merged changes be escalated to python-dev for further discussion, and potentially even reverted prior to release. You are expected to subscribe to python-committers, python-dev, python-checkins, and one of new-bugs-announce or python-bugs-list. Submitting a contributor form for Python licenses any code you contribute to the Python Software Foundation.

While you retain the copyright, giving the PSF the ability to license your code means it can be put under the PSF license so it can be legally distributed with Python. This is a very important step! Hopefully you have already submitted a contributor agreement if you have been submitting patches.

But if you have not done this yet, it is best to do this ASAP, probably before you even do your first commit so as to not forget. Also do not forget to enter your GitHub username into your details on the issue tracker. Once you have your commit privileges on GitHub you will be able to accept pull requests on GitHub. First and foremost, be a good person. This might sound melodramatic, but you are now a member of the Python project and thus represent the project and your fellow core developers whenever you discuss Python with anyone.

We have a reputation for being a very nice group of people and we would like to keep it that way. Second, please be prompt in responding to questions. Many contributors to Python are volunteers so what little free time they can dedicate to Python should be spent being productive. It is completely acceptable to say you are too busy, but you need to say that instead of leaving people waiting for an answer. This also applies to anything you do on the issue tracker.

Third, please list what areas you want to be considered an expert in the Experts Index.

This allows triagers to direct issues to you which involve an area you are an expert in. But, as stated in the second point above, if you do not have the time to answer questions promptly then please remove yourself as needed from the file so that you will not be bothered in the future. Once again, we all understand how life gets in the way, so no one will be insulted if you remove yourself from the list.

I have in my Dockerfile now:. This is the option I recommend: it's clean, there's no risk to mess up your system and you have full control on what you get.

Moreover 1. Download the archive and follow the instruction on the Getting Started guide. This is what OP did. If you don't want to build Boost. Python yourself, you can bypass apt and its dependencies cheking with dpkg.

Let's say you want to install a package named foo which depends on bar and bazbut you don't actually need baz. Notice that apt will still complain about unresolved dependencies but hey, that's its jobso the problem is not entirely solved: you just swept it under the carpet. This is new to me. Apparently, you can create dummy packages to fulfill the dependencies. As I said, I've never used equivs before, but you can find out more about it here.

Home Questions Tags Users Unanswered.Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python.

The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience. The first exercises work on basic Python concepts like strings and lists, building up to the later exercises which are full programs dealing with text files, processes, and http connections.

The class is geared for people who have a little bit of programming experience in some language, enough to know what a "variable" or "if statement" is. Beyond that, you do not need to be an expert programmer to use this material. To get started, the Python sections are linked at the left -- Python Set Up to get Python installed on your machine, Python Introduction for an introduction to the language, and then Python Strings starts the coding material, leading to the first exercise.

The end of each written section includes a link to the code exercise for that section's material. The lecture videos parallel the written materials, introducing Python, then strings, then first exercises, and so on. At Google, all this material makes up an intensive 2-day class, so the videos are organized as the day-1 and day-2 sections.

And finally thanks to Google and my director Maggie Johnson for the enlightened generosity to put these materials out on the internet for free under the Creative Commons Attribution 2.
