  • Executive Summary: The Python Software Foundation

    ...if an entirely different programming language were named "Python" or even "Python Plus", it could cause considerable confusion, making life more difficult for the developers and users of either language. Any other Pythons should be the same programming language, within reason, even if they implement the language differently as do IronPython and Stackless Python. Similarly, the Python logos must refer only to the Python programming language and they should not be modified in a...

    ...iff, which I would apply to my work version of Python, and if I liked it, I would check it into my CVS source tree. (CVS is a source code version management system, and the subject of several books.) Bug reports followed the same path, except I also ended up having to come up with the patch. Clearly, with the increasing number of contributions, my inbox became a bottleneck. What to do? Fortunately, Python wasn't the only open source project with this problem, and a few smart people ...

  • Proposed Improvements to Module Cleanup

Algorithms When a Python interpreter is deleted, its variables and modules are "cleared carefully" in a partially specified order. The operation "clear carefully" is defined below; it effectively deletes the module's variables in a partially specified order. M1. Before anything else, the following variables are set to None (not necessarily in this order): __builtin__._ sys.exc_{type...

Instead of using a GPG key for verification, use the above table to choose which signing identity and OIDC issuer is expected for each Python release version. After an artifact has been verified using GPG, it's common to pin the artifact to a specific checksum value like SHA-256. If this value is already available, it's possible to check the validity...

For example, if cell phones were programmable, one would still use the regular domain-specific interface (the keypad) to dial a specific number, since that's the most convenient way to access that specific functionality. However, without programmability, there is no way to make it try several different numbers for a particular friend until one is answered, unless the cell phone vendor anticipated this particular feature. Why Start with Python? We propose to start by maki...
