  • What's New In Python 3.0

    ...python interpreter, some environment variables would grow without limit. Issue #3643: Added a few more checks to _testcapi to prevent segfaults by exploitation of poor argument checking. bsddb code updated to version 4.7.3pre2. This code is the same than Python 2.6 one, since the intention is to keep an unified 2.x/3.x codebase. The Python code is automatically translated using "2to3". Please, do not update this code in Python 3.0 by hand. Update the 2.6 one and then do "2to3"...

  • Python Success Stories

    ...Python I had used Python for small scripting projects before, and liked its quick-off-the-blocks feel. It would provide me with a malleable environment in which to experiment with features, to see what Nat would find interesting. Although this was an at-home project to be used only by my son, it shared issues with larger, supposedly more serious projects: unclear requirements, unpredictable customers, and limited developer resources. The most important concern to me in choosing the developmen...

  • What's new in Python 2.3

    ...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 SourceForge) is now ...

  • Comparing Python to Other Languages

    ...Python programs are typically 3-5 times shorter than equivalent Java programs. This difference can be attributed to Python's built-in high-level data types and its dynamic typing. For example, a Python programmer wastes no time declaring the types of arguments or variables, and Python's powerful polymorphic list and dictionary types, for which rich syntactic support is built straight into the language, find a use in almost every Python program. Because of the run-time typing, Python's ru...

  • 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...
