Re: Rookie question about data types (hashtables)

the bsddb module has a binary tree database but that might be overkill. Other than that I doubt there's anything in standard python that would help. If you don't plan to add any words to your dictionary you could order the list and use a binary search to find the entries. you could use python list for that :-)

win32com - .ocx won't Dispatch...
by RJ Jan. 29, 2004

Jan. 29, 2004

Hi, I've been going over the Quick Start to Client side COM and Python and many other sources, but cannot find an example that will get my com/ActiveX .ocx USB device driver imported. The Excel and Word examples run fine. win32com.client.Dispatch("Excel.Application") etc., but how does one know the ("<foo>.<bar>") to type in? Excel looks only vaguely like "Excel.Application" in the com browser. Firstly, I found the ocx from the Python Object Browser. I ran makepy.py on EDREUtlX.ocx (USB device driver) which created 8AA34F82-95C9-11D3-8EB6-00C0DF2247CAx0x3x5.py etc. in gen_py\, but, I cannot find a syntax to get Dispatch to accept it... from win32com.client import Dispatch # failed attempts Dispatch("EDRE Utility Control") # name in browser Dispatch('{8AA34F82-95C9-11D3-8EB6-00C0DF2247CAx0x3x5}') Dispatch('{8AA34F82-95C9-11D3-8EB6-00C0DF2247CA}') Dispatch("8AA34F82-95C9-11D3-8EB6-00C0DF2247CA") Dispatch("8AA34F82-95C9-11D3-8EB6-00C0DF2247CAx0x3x5") all return: Traceback (most recent call last): File "<stdin>", line 1, in ? File "C:\Python23\lib\site-packages\win32com\client\__init__.py", line 95, in Dispatch dispatch, userName = dynamic._GetGoodDispatchAndUserName(dispatch,userName,clsctx) File "C:\Python23\lib\site-packages\win32com\client\dynamic.py", line 84, in _GetGoodDispatchAndUserName return (_GetGoodDispatch(IDispatch, clsctx), userName) File "C:\Python23\lib\site-packages\win32com\client\dynamic.py", line 72, in _GetGoodDispatch IDispatch = pythoncom.CoCreateInstance(IDispatch, None, clsctx, pythoncom.IID_IDispatch) pywintypes.com_error: (-2147221005, 'Invalid class string', None, None) So, what is the required syntax? Thanks, Ray

Oracle db connection problem solved
by John Benson Jan. 29, 2004

Jan. 29, 2004

Thanks much for help with the Oracle db connection problem. That, plus some local assistance getting the sqlnet.ora default domain right, got everything fixed. Now I'm connected, and have been able to retrieve information from Oracle into my PC Python session. I seem to see a lot of advice asking people to google before submitting a problem to the list. This was nicely illustrated by the suggestion to google on the verbatim Oracle database error code. I was amazed to see all the stuff it brought up, and I'll certainly add googling for even proprietary error codes to my bag of tricks. Thanks again.

Problems with python23_d.lib built with Visual Studio 7.1
by Paton J. Lewis Jan. 29, 2004

Jan. 29, 2004

I built the Python 2.3.3 sources with Visual Studio 7.1 (the conversion of the Visual C++ 6 project files appeared to work without a hitch). Everything seems fine except when I try to link my project with the debug Python library, in which case I get unresolved symbols apparently because the Python debug library symbol names have been modified in an unexpected fashion. For example, the calling code asks for symbol __imp__Py_InitModule4 (which exists in python23.lib) but python23_d.lib contains __imp__Py_InitModule4TraceRefs. Has anyone run into this problem before? Thanks, Pat

executing an external app
by Joseph Krauze Jan. 29, 2004

Jan. 29, 2004

Hi all, I have a simple question which I cannot solve (relatively new to Python). I want to write a script that executes an application on the go. I looked into the exec*e() calls but the problem there is that they do not return. I also looked into execfile() but here the PATH is not taken into account and I couldn't figure out to pass the file that's executed arguments. So, is there a simple way to execute an external app? i.e. execvpe('cat', 'myFile') - this will not return Thanks, Joseph

Problem connecting to https using ZSI (openssl problem) - python2.3
by Adil Hasan Jan. 29, 2004

Jan. 29, 2004

Hello, I'm having problems trying to use ZSI to connect to a https url. I give the command and I get prompted for my X509 cert pass-phrase, but the program dies with an openssl error. Here's my code: from ZSI import * u='' n='https://shahzad.fnal.gov/edg-voms-admin/uscms/services/VOMSAdmin' b = Binding(url=u,ns=n, ssl=1, \ host='shahzad.fnal.gov',port=8080, \ cert_file='/home/hasan/.globus/usercert.pem', \ key_file='/home/hasan/.globus/userkey.pem') b.listCAs() The traceback I get is: Enter PEM pass phrase: Traceback (most recent call last): File "<stdin>", line 1, in ? File "/usr/local/python2.3/lib/python2.3/site-packages/ZSI/client.py", line 28, in __call__ requesttypecode=TC.Any(self.name, aslist=1)) File "/usr/local/python2.3/lib/python2.3/site-packages/ZSI/client.py", line 131, in RPC self.Send(url, opname, obj, **kw) File "/usr/local/python2.3/lib/python2.3/site-packages/ZSI/client.py", line 184, in Send self.h.connect() File "/usr/local/python2.3/lib/python2.3/httplib.py", line 961, in connect ssl = socket.ssl(sock, self.key_file, self.cert_file) File "/usr/local/python2.3/lib/python2.3/socket.py", line 73, in ssl return _realssl(sock, keyfile, certfile) socket.sslerror: (1, 'error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol') Any ideas about this? Does anyone know how to solve this problem? I have seen one post here with a similar problem, but haven't seen any resolution. Help! thanks, adil

RE: comparing booleans
by Delaney, Timothy C (Timothy) Jan. 28, 2004

Jan. 28, 2004

> From: Gerrit Holl > > is it proper to compare booleans? It is possible, of course, because > they're compatible with numbers, but booleans aren't truly > numbers. Actually, they *are* really numbers ... >>> isinstance(True, int) True >>> isinstance(False, int) True >>> True == 1 True >>> False == 0 True >>> True == 2 False Note the last case - you can't just compare any true value with True and expect that the comparison will compare True - it must explicitly equal 1 (or True). Likewise with False. However, if `extends` is definitely boolean in your example, then it's perfectly reasonable to do: return cmp(self.extends, other.extends) if you want False to be considered less than True.
