  • 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".

  • 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...
