Welcome! This page contains instructions for prospectivegetting OPWstarted andwith Googlecontributing to Python. They cover practicing Summersome of Codethe internscommon tools of open source development, as well as anyonesteps else interested infor contributing specifically to Python.
 
These instructions were written for prospective [http://wiki.python.org/moin/OPW/2014 GNOME Outreach Program for Women] and [http://wiki.python.org/moin/SummerOfCode/2014 Google Summer of Code] interns, but are relevant for anyone interested in contributing to CPython and the standard library.

== Goal #1: install an IRC client ==
 
[[File:Chat.png|100px]]
 
IRC is a real-time chat protocol that open source projects often use to talk about the project and as a medium for users and developers to help each other.

== Goal #2: practice navigating from the command line ==
 
[[File:Utilities-terminal.png|100px]]
 
Many of the tools of open source development are primarily used via the command line. Let's get some practice with navigating the computer from the command line.

== Goal #3: Get familiar with the Python bug tracker ==
 
[[File:Bug.png|100px]]
Python tracks bugs and features at http://bugs.python.org/.
 
First,Python pleasetracks createbugs anand accountfeatures onat http://bugs.python.org/. Please create an account on this site now.
 
Next, please familiarize yourself with how Python uses its bug tracker by exploring and finding answers to the following questions:
 
# What is the oldest open Python ticket?
# How many open issues need a patch?
# How many "critical"-level open issues are there?
 
 
== Goal #4: practice using version control ==
 
[[File:History.png|100px]]
 
Mercurial is the distributed version control system Python uses to manages changes to its code.
 
Please [http://mercurial.selenic.com/downloads/ download and install Mercurial now].
If you have not used Mercurial before, please go through this tutorial: http://hginit.com/
 
If you have not used Mercurial before, please go through this tutorial: [http://hginithgbook.red-bean.com/read/a-tour-of-mercurial-the-basics.html this tutorial].
 
 
== Goal #5: practice creating patches ==
 
[[File:Patch.png|100px]]
 
Code changes are represented in a concise and standard format called a "diff". <tt>patch</tt> is a utility which applies a "diff" to someone else's copy of the code.

== Goal #1: join the mailing list ==
 
[[File:Email.png|100px]]
Join the Python core-mentorship mailing list and introduce yourself: https://mail.python.org/mailman/listinfo/core-mentorship.
 
The Python community has a lot of mailing lists. The 2 big ones for new contributors are:
 
# [http://mail.python.org/mailman/listinfo/core-mentorship core-mentorship]: This is a great place to ask questions about contributing, ask for reviews, and get suggestions for bugs to work on.
# [http://mail.python.org/mailman/listinfo/python-dev python-dev]: The main mailing list for developing and releasing Python. Please do not ask general Python questions on this list.
 
Join the PythonThe core-mentorship mailing list andwill introducebe yourself:our focus as we get settled in, so please https[http://mail.python.org/mailman/listinfo/core-mentorship join the list] now.
 
 
== Goal #2: read the developer guide ==
 
[[File:Safari.png|100px]]
Read the Python developer guide: http://docs.python.org/devguide/
 
Python has excellent documentation for getting started with contribution in its developer guide: http://docs.python.org/devguide/
 
Please read through the following sections of the developer guide:
 
# [http://docs.python.org/devguide/#quick-start Quick start]
# [http://docs.python.org/devguide/setup.html Setup]
# [http://docs.python.org/devguide/help.html Where to get help]
# [http://docs.python.org/devguide/patch.html The lifecycle of a patch]
# [http://docs.python.org/devguide/runtests.html Writing and running tests]
# [http://docs.python.org/devguide/tracker.html#tracker Using the issue tracker]
# [http://docs.python.org/devguide/devcycle.html The CPython development cycle]
 
By the end, you'll:
 
* Have downloaded the Python source code
* Built Python
* Run the test suite
* Have an overview of the development cycle.
 
Don't worry if this doesn't feel fully digested yet! The process will become clearer with practice.
 
 
== Goal #3: pick a bug to work on ==
 
[[File:Debugging.png|100px]]
 
It's time to pick a Python bug to work on! Visit http://bugs.python.org/ and browse for one that looks good.
 
It's a bit of an art to determine if a bug is good for a new contributor, so here are some suggestions:
 
First, the developer guide suggests 2 good areas for first-time contributors:
 
# [http://docs.python.org/devguide/docquality.html Documentation]
# [http://docs.python.org/devguide/coverage.html Test coverage]
 
If those sound interesting to you, look for issues in those areas.
 
Next, for the office hours on Sunday, March 9th, we'll have a list of beginner-friendly bugs. Check back here on Sunday to review that list.
 
Finally, you can always ask for help or suggestions on the core-mentorship mailing list or in the <tt>#pyladies</tt> IRC channel.

ReadFollow the Pythonsteps in the developer guide to create and submit a patch for your bug: http://docs.python.org/devguide/patch.html.
 
Make sure to run the test suite first and that the tests all still pass!
