  • Bugs in Python 2.3.2

    Bugs in Python 2.3.2 <h3>Bugs in Python 2.3.2</h3> <ul> <li>IDLE now executes code in a separate process. To communicate between the main process and executing processes, IDLE opens a socket to 127.0.0.1 (the local machine). Some firewalls running on Windows machines interfere with this and can cause either silent failures or erroneous popup windows from the firewall. This problem only occurs if you run a firewall on the same machine as IDLE.</li> </ul> &...

  • Community Stories

    Community Stories Packaging People who need to install Python packages get confused a lot. That's not their fault; that's because the volunteers who maintain the packaging tools don't have enough time to get everything organized so that it's clear and easy to use. In the last few years, the PSF has gotten grants and used that money to massively improve packaging. We overhauled PyPI and we're making pip more consistent, with genuine attention to user experience. With more funding, we can finall...

    ...compilation (although static error checking tools like PyChecker are now available for this problem). Another was a result of the very seamless way in which Python casts between object and data types. While this feature allows for quick and flexible code, it is the responsibility of the programmer to make explicit the data types that a function expects. A standard coding style that names variables according to their expected data type is an easy way to address this problem. A 30-day evaluation o...

    ...compilation of page templates to Java Server Pages that are ultimately used to deliver the content to the web. By using XIST tag libraries instead of JSP tag libraries we are able to build optimized Java Server Pages that run considerably faster than their JSP tag library counterparts, without any changes to the JSP files. This performance gain is a result of the fact that the XIST preprocessor takes care of many compute-intensive operations, that might require dynamic type introspection, string...
