any json data validation library recommendation?
Hi I'm writing json data validation tool in a language other than python, but knowing that there is plenty of good tools for it, I am looking for inspiration here. I am aware of json schema standard, but on its own its rather verbose and I'd rather have models defined in code (directly or via some DSL). Can anyone recommend library that provides good API for declaring data schemas, so I could see how it could be done? (Doing it is not a problem. Doing it in a way that's convenient for users, readable and generates good error messages is something I care about).

Python package index in elasticsearch
Hi Being frustrated with speed and inflexibility of pip search, I played with elasticsearch and set up my own index. Maybe someone will find it useful too. Site:http://pypisearch.linuxcoder.co.uk Code: https://github.com/Fiedzia/pypisearch Full lucene syntax is allowed. Note: indexing is in progress, but over 60% of pypi packages are there, it should get to 100% within max few hours. Having the basics working, I hope to polish it soon.

Floating points values use finite amount of memory, and cannot accurately represent infinite amount of numbers, they are only approximations. This is limitation of float type and applies to any languages that uses types supported directly by cpu. To deal with it you can either use decimal.Decimal type that operates using decimal system and saves you from such surprises (but it will be much slower and incompatible with c code that doesn't handle decimals or converts them to floats) or use epsilon for every comparison and rounding/formatting with limited precision for displaying.

Because these three are the only ones i know of that are popular and free. A standard answer is - use that one, which is known to your friends, so they can help you. Actually all Linux distros come with python and huge amount of additional modules, so choose any. Fedora, Mandrake, Suse and Ubuntu willi be easier for begginers, as they are targeted on inexperienced Linux users (what doesn't mean they cannot be used by experienced), Debian requires some knowledge (well, way more then other distros) but i like it for its clarity, wonderful package manager apt and control i have over it, it is also well documented and popular.

Why is that better than Python creating a HOME in os.environ, if it doesn't already exist? I can think of a few reasons it's better, and a few reasons it's worse. First, it is possible that HOME viariable already exists and has different meaning, (if python is used as embedded scripting language it can be defined by application), Second, there is a group of path related functions in os.path (or ntpath), including expanduser, and its better to use function than relay on some interpreter behaviour that may be different on jython or ironpython. -- Maciej Fiedzia Dziardziel (fiedzia (at) fiedzia (dot) prv (dot) pl) www.fiedzia.prv.pl How come in Scooby Doo Fred and Daphne were always on the same team and Velma, Scooby and Shaggy were always on the same team?

Its maybe 10-20 lines of trivial code, so i suggest you to read python tutorial, unless its only do-it-once operation. Do you really need to create 30k files? this will take a lot of time (creating a file is time-consuming operation on creation, sending them to server too) and disk space greedy - even if file has 300 bytes, it may take 4kb or more on disk, depending on filesystem and its settings.

Re: PyGTK vs. wxPython
dcrespo wrote: Hi all... I think wxPython is much better than PyGTK. First of all, PyGTK needs the GTK runtime installed, whereas wxPython is entirely Python's modules, so It facilitates the apps' distribution. As already mentioned, it is not true. You will still need GTK (on Linux, not on Windows). Also, PyGTK uses specific controls or widgets of GTK, while wxPython uses native controls of the platform where the app is running. Which has both pros and cons. wx unification isn't perfect (i had some problems with drawing that required some workarounds specific to a platform), it also doesn't allow you to really (or at least easy) use platform specific functionality (GTK app can be easily convert to GNOME app). I'm learning both, but at a slow step, so I want to know all the comments about this subject in this group. Go to www.pygtk.org, there are many tutorials, faq and other documentation and try it. I heard about Glade to make the graphic layout of the app and then export it as XML. Then, it connects to PyGTK. The problem I see is that What if you want to refer to a state of a specific radiobutton of a radobutton's group? It seems to be very troublesome. Do not listen, just test it. For me glade is the best way to define user interface. This is the way GUI should be created IMHO. You can access any widget just by calling its name - you will find details in any glade tutorial. Please, post any comments about the pros and cons of each library, and the proper way to construct the graphic layout (generating XML through Glade, or by hand-code). Thanks. I don't have much experience with GTK on Windows, but i really like on Linux, way more then wx.
