    An introduction to Web Scraping with Python and Azure Functions

  • Python Patterns - An Optimization Anecdote

    ...Python-C API, so I expected at most modest speed up compared to f7(). Given the effort of writing and testing an extension (compared to whipping up those Python one-liners), as well as the dependency on a non-standard Python extension, I decided not to pursue this option... Conclusion If you feel the need for speed, go for built-in functions - you can't beat a loop written in C. Check the library manual for a built-in function that does what you want. If there isn't one, h...

  • SIG for development of Python/C++ integration

    ...Python for wrapped C++ functions. Generic C++ to Python Object Interface It is often necessary for C++ functions to manipulate objects passed to them directly from Python, without converting them to some other representation. Currently Boost.Python has undocumented support for that usage when the expected Python type is known. Goal: Addition of a C++ type which wraps any Python object and provides a similar interface to Python's, with the validity of any operat...

  • Highlights: Python 2.4

    ...Python prior to 2.4a2 would leave a broken module in sys.modules - subsequent attempts to import the failing module would silently succeed, but use the broken module object. The import machinery now removes the failing module from sys.modules if the import fails. The -m command line option - python -m modulename will find a module in the standard library, and invoke it. For example, python -m pdb is equivalent to python /usr/lib/python2.4/pdb.py New or upgraded built-ins built-in sets - th...

  • Proposed Improvements to Module Cleanup

    ...Python function or class. A function object contains a reference to the function's 'globals' object, which is the __dict__ of the module that defines it. Since the __dict__ normally has a reference to the function there's a cycle that needs to be broken, or else the __dict__ would never be garbage collected. Note that a reference-count based solution doesn't work within one module, since references between functions are by name, not by value -- two mutually recursive functions can st...

  • Debugging Reference Count Problems

    ...Python/C API manual again, and then carefully read the descriptions of the functions you're calling. (I know, the manual is not complete; but it isn't *that* incomplete, and if you're finding a function that's not in the manual, reading its source usually gives a clue.) So says I (beginning to talk to self), why not print the environment in which the functions are being run to see what's going on... no sooner said than done. And the error disappeared! Take the printing line out -...

  • Metaclasses in Python 1.5

    ...Python 1.5 Metaclasses in Python 1.5 (A.k.a. The Killer Joke :-) (Postscript: reading this essay is probably not the best way to understand the metaclass hook described here. See a message posted by Vladimir Marangozov which may give a gentler introduction to the matter. You may also want to search Deja News for messages with "metaclass" in the subject posted to comp.lang.python in July and August 1998.) In previous Python releases (and still in 1.5), there is something c...

    ...Python 2.4 beta 2? Release date: 03-NOV-2004 License The Python Software Foundation changed the license under which Python is released, to remove Python version numbers. There were no other changes to the license. So, for example, wherever the license for Python 2.3 said "Python 2.3", the new license says "Python". The intent is to make it possible to refer to the PSF license in a more durable way. For example, some people say they're confused by that the Open Source Ini...

  • Glue It All Together With Python

    ...Python website http://www.python.org. Like Tcl, Python is easily extensible with C/C++/Java code, and easily embeddable in applications. Python even uses Tk, the Tcl GUI toolkit, for a de-facto standard portable GUI toolkit. Unlike Tcl, however, Python supports object-oriented programming. Python programmers can create classes, use multiple inheritance, define methods, overload operators, and so on. Python's Strengths Syntactically, Python code looks like executable pseudo cod...

Most of Mac/Lib has moved to Lib/plat-mac, which is again used both in MacPython-OSX and MacPython-OS9. 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 ...

The result is a language that scales well from small scripts written by a chemist to large packages written by a software developer.

Refactoring the Perl code without moving to Python would have produced c...
