problem building Python in MachTen Unix
by William C. Brennan May 3, 2000

May 3, 2000

Please, someone save me from Perl! I'm trying to build Python from sources to work under Tenon's CodeBuilder Unix (MachTen Lite), which is a BSD variety which runs under the MacOS. (Yes, Unix _under_ the MacOS). I want to use Python because I'm frustrated by my inability to understand even my own Perl scripts, let alone other folks'. Python looks like it has everything I want. I've downloaded and unpacked the Python source, and run the configure script without error. Among the many lines of information, it displays: checking for --with-next-framework... no checking for --with-dyld... required for framework build When I proceed to performing the "make", I get an error while making the object files in tho Python sub-directory: gcc -g -O2 -I./../Include -I.. -DHAVE_CONFIG_H -c getversion.c -o getversion.o gcc -g -O2 -I./../Include -I.. -DHAVE_CONFIG_H -c graminit.c -o graminit.o gcc -g -O2 -I./../Include -I.. -DHAVE_CONFIG_H -c import.c -o import.o gcc -c -g -O2 -I./../Include -I.. -DHAVE_CONFIG_H -I/ ./importdl.c ./importdl.c:269: mach-o/dyld.h: No such file or directory make[1]: *** [importdl.o] Error 1 make[1]: Leaving directory `/my/Python-1.5.2/Python' which implies to me that the configure script thinks my "with-dyld" or "with-next-framework" settings are set. It looks like I need to tell the configure script that I'm running without frameworks and without dyld, but my attempts to communicate this to the configure script have failed. I've tried: ./configure --without-next-framework --without-dyld which has worked even less well. I've also tried manually editing the configure script (which is almost totally unintelligible to me) by changing the defaults at the top from: ac_help="$ac_help --with-next-framework Build (OpenStep|Rhapsody|MacOS10) framework" ac_help="$ac_help --with-dyld Use (OpenStep|Rhapsody|MacOS10) dynamic linker" to ac_help="$ac_help --without-next-framework Build (OpenStep|Rhapsody|MacOS10) framework" ac_help="$ac_help --without-dyld Use (OpenStep|Rhapsody|MacOS10) dynamic linker" which hasn't worked either. I've looked through the configure script to see if I could figure out any other flags which may indirectly cause "with-next-framwork" or "with-dyld" to be set, but I can't find anything. Could someone suggest something to this naive Python builder to get his "make" script to work? Thanks! -- bill -- Bill Brennan brennanw(a)pond.com

Python COM troubles
by remove.me.wwicker＠spectratechnologies.com May 3, 2000

May 3, 2000

I'm trying to use Python with SolidWorks, a really cool CAD package. SolidWorks has a COM interface which plays reasonably well with Python. Unfortunately, the interface does not seem to provide run-time type info. This appears to confuse the gen_py interface, which means that all of my dispatch objects are dynamic. (bummer) In turn, this looks like it means that I cannot use DispatchWithEvents, as it seems to rely on the gen_py library being recognizable. Is there a way around this appearance of typelessness? There is a type library, and I've run make-py successfully. I just can't see an easy way into it. It should by now be evident that I know little about Python, and less about COM. Enlightenment welcome. And now for something completely different: COM dispatch methods that are documented to return SAFEARRAYS of dispatch pointers fail with pythonwin v125 and 128 (the only ones I've felt safe enough to try). The traceback is something like this: >>> import win32com.client >>> swx = win32com.client.Dispatch("SldWorks.Application") >>> adoc = swx.ActiveDoc #get the active model >>> sel = adoc.SelectionManager #get the current list of selected objects >>> sel.GetSelectedObjectCount #how many are there? 1 >>> face = sel.GetSelectedObject3(1) #I already know that I selected a face, so lets get it. >>> face <COMObject <unknown>> >>> edges = face.GetEdges() #should return a tuple full of dispatch pointers to edge objects... Traceback (innermost last): File "<interactive input>", line 1, in ? File "C:\tools\Python\win32com\client\dynamic.py", line 393, in __getattr__ ret = self._oleobj_.Invoke(retEntry.dispid,0,pythoncom.DISPATCH_PROPERTYGET,1) SystemError: NULL result without error in call_object >>> Suggestions?

Newbie Question
by Arnaldo Riquelme May 3, 2000

May 3, 2000

Suppose I have a file name tick.tkr that looks like this SUNW. MFST. FOO. SPAM. MOO. End_Of_File I want to read the file into a list myfile = open("tick.tkr", "r") mylist = myfile.readlines() Now I have mylist with the contents of tick.tkr. "mylist" looks like this ['SUNW.\012', 'MSFT.\012', ..........'End_of_File/012'] How do I read the file into a list without getting the newline character, so I can accomplish this for tic in mylist: #create file tic.prn I know the other P language has something like 'chop' or something like that, but I'm not going there. Thanks Arnaldo,

I did not follow the implementation discussions, but from the outside, it looks like 8-bit strings are kept and will be speedy. People should either: 1) use them for ASCII without bothering or thinking much, 2) write Python source files in UTF-8, relying on the default encoding, 3) explicitly "cast" the encoding while converting strings to Unicode. My guess is that 2) is not such good style, even if we know it will likely be used in programs. This might be convenient for speed prototyping, or interactive use, say. Python already has these two level of languages, comparable to spoken English versus written English, the former being more relaxed, and the latter more formal. There are many things I let me write in interactive Python that I conscientiously avoid in saved scripts. That should probably be the case of 2). Better would be to always use 3) for non-ASCII strings which are not directly Unicode. The notion of good style would almost turn invalid UTF-8 in 8-bit strings into an academical problem, and one more reason to avoid 2). -- François Pinard http://www.iro.umontreal.ca/~pinard

If you're trying to put the info on disk to read it in again later, look at eval(repr()), eg: >>> a,b,c = eval(repr((1.2, -3.5, 10))) >>> a,b,c (1.2, -3.5, 10) >>> Emile van Sebille Louis M.

converting word documents to html
by Joe Saltiel May 2, 2000

May 2, 2000

Hey, I was wondering if anybody had done any work on converting word processors type documents to html. (word or word perfect, pdf or anything else). I am looking for a nice way to post documents online that are laden with footnotes/endnotes. Word2000 does an allright job, but adds a bunch of junk that makes the file 3-4 larger then it has to be. I was thinking of writing something to do that but just want to check before I reinvent the wheel..... thanks Joe

ODBC / DBI help (via Win32 Extensions)
by junkster＠nospam.rochester.rr.com May 2, 2000

May 2, 2000

==================================================== (Remove "NoSpam" to Email me) ==================================================== Hi All, I'm doing some MS Access/SQL work via the ODBC & DBI modules... and it's working great... I've got the read, and most of the "write" functions working fine, except when it comes to utilizing the date values... I can read and convert the date information into a python readable value.... But I can't seem to do an UPDATE or INSERT INTO command with a date value inside it. Can someone possibly post a example, or a fragment of a working UPDATE / INSERT INTO command? Or point me to some python resources that might assist? I've checked the ODBC how-to's on the python web site, and they don't even touch on the subject of WRITING a date... The examples on reading were very informative, but obviously I'm doing something wrong. - Benjamin ==================================================== (Remove "NoSpam" to Email me) ==================================================== Please feel free to copy any and or all of this sig.

Discrepency between JPython and CPython
by Venkatesh Prasad Ranganath May 2, 2000

May 2, 2000

Hi, Consider the expression str(1.14 * 200). In CPython it yields 228.0 In JPython it yields 227.99999999999997 Shouldn't this result in consistent values across variuos implementation? If so, which of the implementation is buggy? I think it is JPython, may be I am wrong. -- Venkatesh Prasad Ranganath e-mail: rvprasad(a)cis.ksu.edu, rvprasad(a)ksu.edu Address: Department of Computing and Information Science, 234 Nichols Hall, Kansas State University, Manhattan, KS 66506 Phone: (785)-532-6350 Extn: 48
