Python is a mature programming language which has established a reputation for stability. In order to maintain this reputation, the developers would like to know of any deficiencies you find in Python.
Bug reports should be submitted via the Python Bug Tracker (http://bugs.python.org/). The bug tracker offers a Web form which allows pertinent information to be entered and submitted to the developers.
The first step in filing a report is to determine whether the problem has already been reported. The advantage in doing so, aside from saving the developers time, is that you learn what has been done to fix it; it may be that the problem has already been fixed for the next release, or additional information is needed (in which case you are welcome to provide it if you can!). To do this, search the bug database using the search box on the top of the page.
If the problem you’re reporting is not already in the bug tracker, go back to the Python Bug Tracker. If you don’t already have a tracker account, select the “Register” link in the sidebar and undergo the registration procedure. Otherwise, if you’re not logged in, enter your credentials and select “Login”. It is not possible to submit a bug report anonymously.
Being now logged in, you can submit a bug. Select the “Create New” link in the sidebar to open the bug reporting form.
The submission form has a number of fields. For the “Title” field, enter a very short description of the problem; less than ten words is good. In the “Type” field, select the type of your problem; also select the “Component” and “Versions” to which the bug relates.
In the “Comment” field, describe the problem in detail, including what you expected to happen and what did happen. Be sure to include whether any extension modules were involved, and what hardware and software platform you were using (including version information as appropriate).
Each bug report will be assigned to a developer who will determine what needs to be done to correct the problem. You will receive an update each time action is taken on the bug.
