Hierarchical unit tests
by Pupeno Aug. 2, 2006

Aug. 2, 2006

Hello, Having A(unittest.TestCase) and B(A), the unittests framework seems not to run A's test when testing B, right ? If so, is there any way to 'fix' it ? that is, make all tests in A, also run for B ? Thanks. -- Pupeno <pupeno(a)pupeno.com> (http://pupeno.com)

The 'b = foo' statement binds together name b and the object foo - which in this case happens to be a class.

Finding the name of a class
by Kirk Strauser Aug. 2, 2006

Aug. 2, 2006

Given a class: >>> class foo(object): >>> pass how can I find its name, such as: >>> b = foo >>> print something(b) 'foo' I'm writing a trace() decorator for the sake of practice, and am trying to print the name of the class that a traced method belongs to. This seems like it should be easy, but I think I've been staring at the problem too long. -- Kirk Strauser

DLL search path, IDLE versus command line
by h112211＠gmail.com Aug. 1, 2006

Aug. 1, 2006

Hi, Does anyone have any clues why I can import a module (pgdb) from the python command line, but trying to run a script doing it from IDLE I get "ImportError: DLL load failed: The specified module could not be found."? How does the search path differ between IDLE and the Python command line? I'm using Python 2.4.3 on Windows.

You have probably defined your own, say, E somewhere in your module: E = ... # whatever This can easily be fixed by using another name. But what you are really doing wrong is using the from Tkinter import * star-import which drastically increases the likelihood of such name clashes. I recommend using qualified names, abbreviated if you like: import Tkinter as tk ... tk.N + tk.S + tk.E + tk.W ... # a bit longer, but worth the effort Of course this could still go wrong if you do tk = 42 somewhere in your module...

Zipping files/zipfile module

Hi Stephen, some code that I have been using for a similar purpose. def addFolderToZip(myZipFile,folder): folder = folder.encode('ascii') #convert path to ascii for ZipFile Method for file in glob.glob(folder+"/*"): if os.path.isfile(file): print file myZipFile.write(file, os.path.basename(file), zipfile.ZIP_DEFLATED) elif os.path.isdir(file): addFolderToZip(myZipFile,file) def createZipFile(filename,files,folders): curTime=strftime("__%Y_%m_%d", time.localtime()) filename=filename+curTime; print filename zipFilename=utils.getFileName("files", filename+".zip") myZipFile = zipfile.ZipFile( zipFilename, "w" ) # Open the zip file for writing for file in files: file = file.encode('ascii') #convert path to ascii for ZipFile Method if os.path.isfile(file): (filepath, filename) = os.path.split(file) myZipFile.write( file, filename, zipfile.ZIP_DEFLATED ) for folder in folders: addFolderToZip(myZipFile,folder) myZipFile.close() return (1,zipFilename) (success,filename)=createZipFile(planName,files,folders); hope it helps.. cheers ----------------------------------------------------- Thomas Thomas thomas(a)mindz-i.co.nz Phone. +64 7 855 8478 Fax. +64 7 855 8871
