  • Bugs in Python 2.3

    Bugs in Python 2.3 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. IDLE fails to start on Windows if installed to a directory with a space (e.g. C:\Program...

  • Parade of the PEPs

    Parade of the PEPs Parade of the PEPs To start off Developer's Day at the Python10 conference I gave a keynote ending in what I dubbed "the parade of the PEPs". It was a brief overview of all open PEPs, where I gave my highly personal and subjective opinion for each PEP. Later, I realized that this might have been of interest to other developers. I didn't take notes at the conference, so below is a different set of comments that I created from scratch during a single two-hour sitt...

  • What's new in Python 2.3

    What's new in Python 2.3 What's new in Python 2.3 Here are the (subjective) highlights of what's new in Python 2.3. Faster According to a couple of simple benchmark, Python 2.3 is about 20-30% faster than Python 2.2.3. Some of this speed-up was obtained by removing the SET_LINENO opcodes, which means that the difference is less impressive when comparing "python -O"; the rest was various careful tune-ups. New Tools A brand new version of IDLE (from the IDLEfork project at S...
