Adding/removing instance members
by Ladv�nszky K�roly Jan. 30, 2004

Jan. 30, 2004

I understand instance members can be added to an object in a dynamic manner: class Cc: pass oCc=Cc() oCc.x=10 # oCc now has a new member What is the way to remove these instance members? Is it possible to add a new member whose name is given by a string? Thanks on any help, Károly

Sort by key, then by content
by Wayne Folta Jan. 30, 2004

Jan. 30, 2004

As an experiment, I've written a Python script which reads my mailboxes and prints a report on how many messages I've gotten from from each unique sender. I use a dictionary with a key of the email address and each entry is a list with the 0th element being the user's name (if known) and the 1st being the count. At the end, I print the report, sorted by email address. But then I want to print it sorted by frequency of message. What would be the most efficient, idiomatic, iterative, functional way to do that. After some head-twisting (it's way past my bedtime), I finally figured that heapq's would help me, but it seems there should be a cool way to turn the dict into a list (map) and also turn it inside out at the same time... keys = addr_dict.keys () keys.sort () heap = [] for k in keys: print "%s (%s)\t%d" % (k, addr_dict[k][0], addr_dict[k][1]) heapq.heappush (heap, (addr_dict[k][1], k, addr_dict[k][0])) print '*' * 80 while (heap): print "%d\t%s (%s)" % heapq.heappop (heap) Any suggestions?

You can also compile the .py to a python optimized file .pyo. That'll get rid of the comments. Check out the "py_compile" module in the documentation. The easiest way to do it would be to invoke python with the -O flag and import your module to generate the .pyo file.

RE: [Python-Dev] PEP 327: Decimal Data Type
by Michael Chermside Jan. 30, 2004

Jan. 30, 2004

Facundo Batista writes: > I'm proud to announce that the PEP for Decimal Data Type is now published > http://www.python.org/peps/pep-0327.html VERY nice work here. Here's my 2 cents: (1) You propose conversion from floats via: Decimal(1.1, 2) == Decimal('1.1') Decimal(1.1, 16) == Decimal('1.1000000000000001') Decimal(1.1) == Decimal('110000000000000008881784197001252...e-51') I think that we'd do even better to ommit the second use. People who really want to convert floats exactly can easily write "Decimal(1.1, 60)". But hardly anyone wants to convert floats exactly, while lots of newbies would forget to include the second parameter. I'd say just make Decimal(someFloat) raise a TypeError with a helpful message about how you need that second parameter when using floats. (2) For adding a Decimal and a float, you write: I propose to allow the interaction with float, making an exact conversion and raising ValueError if exceeds the precision in the current context (this is maybe too tricky, because for example with a precision of 9, Decimal(35) + 1.2 is OK but Decimal(35) + 1.1 raises an error). I suppose that would be all right, but I think I'm with Aahz on this one... require explicit conversion. It prevents newbie errors, and non-newbies can provide the functionality extremely easily. Also, we can always change our minds to allow addition with floats if we initially release with that raising an exception. But if we ever release a version of Python where Decimal and float can be added, we'll be stuck supporting it forever. Really, that's all I came up with. This is great, and I'm looking forward to using it. I would, though, be interested in a couple more syntax-related details: (a) What's the syntax for changing the context? I'd think we'd want a "pushDecimalContext()" and "popDecimalContext()" sort of approach, since most well-behaved routines will want to restore their caller's context. (b) How about querying to determine a thread's current context? I don't have any use cases, but it would seem peculiar not to provide it. (c) Given a Decimal object, is there a straightforward way to determine its coefficient and exponent? Methods named .precision() and .exponent() might do the trick. -- Michael Chermside

I don't know what it is - but I asked a couple of questions here yesterday... and seem to have received a lot of help from peopel called Peter..... sounds suspiciously like a conspiracy to me :-) Anyway - I couldn't decide between SQLobject and metakit (I'd already seen sqlite but wanted some advuice before I chose one to dive into..). Anyway - the windows download for SQLobject is zero sized - so I've gone for metakit and will have a play. Fuzzy > -- > > http://www.Voidspace.org.uk The Place where headspace meets > cyberspace.
