I'm relatively new to Python programming, and somewhat new to Linux (1.5 years). The last time I tried installing wxPython on Linux, I was unsuccessful. But, it's been a while, and I've learned a lot since then so I may give it a whirl.

Help with EOFError when loading .pyc files
by Carl Bevil March 2, 2003

March 2, 2003

I am having a strange problem. At runtime, I can load a .py file and compile it on the fly without trouble. But if there is a .pyc file already present (generated from from the same .py file), when it is loaded and excuted, I get a runtime error: "EOFError: EOF read where object expected". I've seen this error message in marshal.c, and attempted to do some debugging. But trying to figure out what is going wrong when executing a .pyc file is not easy. :-) So I'm hoping someone out there can give me some hints or advice on what is going wrong. Something that might be relevant is that I am cross-compiling my application for a different platform. The interpreter is embedded into my application. My application is built on the Windows platform, and the .py files are created and saved on the Windows machine. I then run the application remotely (on a proprietary platform), which reads in the .py/.pyc files, either from the PC's hard drive (over the network), or directly from a CD. The reason I bring this point up is that I am concerned this might be some sort of CRLF issue between the two platforms. Although I would think if that were the case, the .py files would not work either. Any ideas? Thanks! Carl

Re: Launching Windows Programs

If you know the filename in advance (or you can get it easy), then you can launch it through command line if you have win32all extensions from Mark Hammond. It would look somthing like this: win32api.ShellExecute(0, "open", '"' + ppFileName + '"', None, None, 1) Where ppFileName is the PowerPoint filename. The "" surrounding it is because the CL have trouble with spaces in the directory. If you need to manipulate the presentation, then the COM interface is the best alternative. -- Andres Rosado Email: andresr(a)despammed.com ICQ: 66750646 Homepage: http://andres980.tripod.com/ Get my PGP key at http://andres980.tripod.com/pgp-key.asc It is easier to resist at the beginning than at the end. -- Leonardo da Vinci

Hope you get > permission soon! :) Nah - unfortunately, that's one of the major parts that's incomplete about it :( A python coverage tool which automatically attaches to multiple threads is a non-trivial task. Of course, if I *do* get to release it (I'm waiting on a VP to sign something off ...) then I could leave it to *someone else* to add the multi-threading part ;) Tim Delaney

I only have one IP on my box so I do not know if this will work for you.. socket.gethostbyaddr(socket.gethostname()) You could probably use the loopback as the parameter, like: socket.gethostbyaddr('localhost') Both of these will return a tuple in the form of (hostname, aliaslist, ipaddrlist). This is in 7.2 of the Python docs if you need to check other variations. -W

Heh. :) Anyway, my basic point remains; I've seen a bunch of creative answers on how to just vote against any such operator, but I think I've seen 4 different ones, and I don't think one should need to be that persistent and creative just in order to vote no.

The thing that is missing from the voting procedure is an explicit way to vote for no change. I guess if we could all read Guido's mind, your way might acheive the same effect but I would prefer that some explicit and unambiguous way to vote for no change (i.e., no ternary expression syntax addition) be built into the voting mechanism. We've seen several methods illustrated in postings, but it isn't clear, at least to me, that any of them are assured to not be reject as invalid votes or if accepted as valid votes, that the intended effect is achieved. My ballot was [A-Q] reject (anything) [A-Q] reject (anything) [A-Q] reject (anything) Rod Haper Gack! Gack! Gack! Gack! Gack! So, how about it Raymond and Laura? Is my ballot a valid vote for no addition of a ternay expression syntax? If not, what's the approved solution? -- Rod +----------------------------------+ | There is a better way ... | | LAP => Linux + Ada95 + Python | +----------------------------------+

The Interface designer isn't really impressive either. QT: Pro's: - does what you expect from a GUI toolkit, haven't looked into it too much though - portable accross unix/windows Con's: - QT is only free under X11, as far as I know Except for Glade, there aren't any good interface builders, and portability to windows is a strict requirement for my project, so I'm currently looking into wxPython.
