  • What's new in Python 1.5 and beyond

    ...Python now have a "Py" or "_Py" prefix, and the same is true for most macros and typedefs. From 1.5a4 to 1.5b1 If you were an alpha tester, here are the most relevant changes since 1.5a4 (of course all known bugs have been fixed, leaks plugged, and some documentation has been added). The full list of changes since 1.5a4 is presented at the end of the Misc/NEWS file. Package directories now require the presence of __init__.py (or .pyc/.pyo as applicable). Packages can no...

  • Using Windows Installer

    ...Python installation. For example, a different installation drive can be specified with TARGETDIR=R:\python24 The default TARGETDIR is [WindowsVolume]Python<version>. Due to a bug in python-2.4.msi, installing into a target dir that has a space in its name causes the IDLE and pydoc shortcuts to fail. Installation for All Users Adding ALLUSERS=1 causes an installation for all users. By default, the non-interactive installation install the package just for the curre...

You can find the product code by looking at the properties of the Uninstall shortcut that Python installs in the start menu. Administrative installation With msiexec /a python<version>.msi an "administrative" (network) installation can be initiated. The files get unpacked into the ta...

  • Parade of the PEPs

    ...Python code broken with this. No array attributes (namely shape, flat, real and imag) for Python versions previous to 2.2 (we use the properties feature to support this for 2.2 and later; so it is only incompatible with Numeric with older versions of Python) There are more minor differences, but these are the major backward compatiblity issues at the Python level. Two of them should not be problems for most users using Python 2.2 or later. It does have a number of importa...

  • Debugging Reference Count Problems

    ...PyObject_GetAttr() and PyObject_GetItem(). On the other hand (and these are the most common examples, but not the only ones), PyList_GetItem(), PyTuple_GetItem(), PyDict_GetItem() and PyDict_GetItemString() all return to you an object without ownership of a reference to the object. This is called a "borrowed" reference. When you pass a borrowed reference to another call that expects you to INCREF its argument (like PyList_SetItem() discussed above), you have a problem. I suspec...

He had begun to use it for a Python version of the BarCamp regional "unconferences", and the idea has proven popular. However, TriZPUG have adopted the PyCamp name for their training seminars, formerly called "Python Bootcamp" (this name seems to have been dropped though). S. Deibel will reply, suggesting the non-exclusive use of "Python Bootcamp" as long as it...

  • Notes

    ...PyDict_Contains(d, k) which is like PySequence_Contains() but is specific to dictionaries and executes about 10% faster. Added three new macros: Py_RETURN_NONE, Py_RETURN_TRUE, and Py_RETURN_FALSE. Each return the singleton they mention after Py_INCREF()ing them. Added a new function, PyTuple_Pack(n, ...) for constructing tuples from a variable length argument list of Python objects without having to invoke the more complex machinery of Py_BuildValue(). PyTuple_Pack(3, a, b, c) is equivalent to...

The only modules remaining in Mac/Lib are specifically for MacPython-OS9 (CFM support, preference resources, etc). A new utility PythonLauncher will start a Python interpreter when a .py or .pyw script is double-clicked in the Finder. By default .py scripts are run with a normal Python interpreter in a Terminal window and .pyw files are run with a window-aware pythonw interpre...

  • EDU-SIG: Python in Education

    ...pygame is the original and still very much active package for game development using Python. It allows Python to talk to SDL, a cross-platform, multimedia library. Because it needs to be compiled for each platform and each Python version, there can be a lag when a new Python version comes along. pyglet is the newcomer, based on OpenGL. Because it is a pure Python package, it can be used as is even when a new Python version is released (except for the Python 2 to Python 3 transition). Miscell...
