Yes - the PEP parade is *very* out of date, and is not maintained. The pronouncement only occurred overnight (from my viewpoint) so you can't expect documents to be updated yet. Basically, Aahz revealed the rejected status to c.l.python with his email. Tim Delaney

looking for a good freelance teacher (paid) for OOP consulting
by Python Baby Jan. 28, 2004

Jan. 28, 2004

I'm learning Python and Object-Oriented Programming from books and online resources. But I really need a good teacher or consultant to have conversations about the OO design of my current projects, and using Python to its best. I would probably need 1-2 hours a week of time, and could pay OK, though not a fortune. It would have to be someone with both teaching experience (good at explaining) and real-world programming experience (good at doing.) Phone calls are fine. Doesn't need to be in person. If interested, please reply to this email (python(a)hitmedia.com) - keeping the subject header the same, so I don't miss it. Thanks!

Nested lists or conditional logic?
by cmichaelbeck＠hotmail.com Jan. 28, 2004

Jan. 28, 2004

this is not all complex, but as a noob i'm having a hard time getting my head around it. i have a list of items. i need to print the items in batches of x, with a summary line after each complete or partial batch, and a total line at the end of the job. if the list looks like ['line1','line2','line3'], and my ITEMSINBATCH = 1, the output should look like this: line1 ---summary line--- line2 ---summary line--- line3 ---summary line--- ---total line--- if ITEMSINBATCH = 2, the output should look like this: line1 line2 ---summary line--- line3 ---summary line--- ---total line--- i've done the following, which works, but it seems like there must be a better/simpler/faster way to do this with nested loops. ideas? # ---------------------Begin code--------------------- ITEMSINBATCH = 1; ARBITRARYNUM = 51; # create a list to work with myList = ['1']*ARBITRARYNUM; for i in range( len(myList) ): # avoid starting at 0 count = i + 1; print "The item is:",myList[i],'\t',count; # ensure that the batch summary line is printed every ITEMSINBATCH # times but not if the number of items is evenly divisible by # ITEMSINBATCH, in which case both the inner print and the outer # print would execute and we'd get consecutive batch summary lines if ( (count) % ITEMSINBATCH ) is 0 and count != len(myList):: print "-----Add batch summary line-----"; # add a final batch line for those trailing items print "------Add batch summary line------And BTW, i is", count; # and add the final summary line print "------Add file summary------"; # ---------------------End code--------------------- TIA, mike

comparing booleans
by Gerrit Holl Jan. 28, 2004

Jan. 28, 2004

Hi, is it proper to compare booleans? It is possible, of course, because they're compatible with numbers, but booleans aren't truly numbers. I'm tempted to write: return cmp(self.extends, other.extends) instead of if self.extends and not other.extends: return 1 else: return -1 # I've already verified self.extends != other.extends ...but somehow comparing Booleans doesn't feel right... Is my feeling correct? (Hmm, makes me wonder, for booleans, are != and ^ equal?) Gerrit. -- 174.

Cross Platform Browser Launcher
by michael＠foord.net Jan. 28, 2004

Jan. 28, 2004

I've written a simple application in python with an HTML help file. I'm looking for a cross platform way of launching the help file. On windows I'd use : os.system('start help.html') Which automatically opens the file with the users browser. Is there a cross-platform way of doing the same thing ? I can do a platform test and use different techniques for different systems - but I don't know how to achieve the same effect on a Linux (Unix ? Mac ?) machine..... Any help appreciated.

linking problems with Python C API
by Jeffrey Holle Jan. 28, 2004

Jan. 28, 2004

I am working on a Linux system using gcc v3.3 and python v2.3.2 I have a problem linking a cpp program to a shared library that uses the Python C API. With just referencing this shared library, I get unresolved references like: PySequence_DelSlice PyNumber_InPlaceXor PyInt_FromLong _PyObject_New This is just a sample, there are actually 130 of similarly named functions. The only other library that I have tried, /usr/local/lib/python2.3/config/libpython2.3.a, causes more trouble, to the point that makes me believe this is a misdirection. Can anybody tell me what library I should be linking to?

Basically, I have to lists. I have to compare them and pick out the difference(s). Maybe the simple/fast approach would be to use a for loop? Thanks,
