splitting by double newline
Hello everybody, I'd like to split a file by double newlines, but portably. Now, splitting by one or more newlines is relatively easy: self.tables = re.split([\r\n]+, bulk) But, how can I split on double newlines? I tried several approaches, but none worked... -- Now the storm has passed over me I'm left to drift on a dead calm sea And watch her forever through the cracks in the beams Nailed across the doorways of the bedrooms of my dreams -- http://mail.python.org/mailman/listinfo/python-list

I tried without ?:, but it didn't work. Can you tell me why is it
important that group is noncapturing?

sending through non-default gateway
Is there a way to create a TCP connection using a gateway of my choice? I have a regular user account on a WinXP machine. It has a DNS server and default gateway configured, and that DNS server and default gateway don't see the rest of the Internet, just the local network. But, I know an IP address of another DNS/gateway pair which is used to access the Internet, and I can ping them (and send nslookup queries) from my machine. So, is there a way to tell python don't use my default gateway, here is an address of the gateway I want you to use? I've been googling, but to no avail... -- Now the storm has passed over me I'm left to drift on a dead calm sea And watch her forever through the cracks in the beams Nailed across the doorways of the bedrooms of my dreams -- http://mail.python.org/mailman/listinfo/python-list

Of course, if you have root/administrator permission, you could probably do it. But if you have that, you could probably just fix the routing table. Yeah, I don't have admin priviledges, it's my office computer which is supposed to be cut of the Internet. I did a bit of reading on source routing and I'd like to try it. Just for fun, in case our router accepts such packets.

downcasting problem
Hi everybody, I need to downcast an object, and I've read repeatedly that if you need to downcast, you did something wrong in the design phase. So, instead of asking how do you downcast in python, let me explain my situation. I have a 2-pass parser. 1st pass ends up with a bunch of superclass object, and 2nd pass is supposed to downcast those to one of subclasses so I can work with them. Details: I have a file full of lines which I parse into Line objects. I also have two subclasses of Line, namely Individual and Family. Constructor of both subclasses needs all Line objects in the file to be constructed, so I cannot construct subclass objects in the first pass. The Python way of doing this (as I understand it) would be to wrap a subclass around Line and have the Line object as an attribute of a subclass. Now, this obviously breaks polymorphism and I now have to reimplement all of Line's classes in subclasses. Although reimplementation is simple (def method(self): return self.line.method()), that way of doing things is just not elegant. So, is there any more elegant solution to my problem? Thanks in advance. -- Now the storm has passed over me I'm left to drift on a dead calm sea And watch her forever through the cracks in the beams Nailed across the doorways of the bedrooms of my dreams -- http://mail.python.org/mailman/listinfo/python-list

subclass constructor problem
I have a superclass Element and a subclass Family. All Family.__init__() does is run Element.__init__() and self.__parse(). For some reason it seems like self.__parse() isn't run.

including constants
Hi there, I have a simple problem and I know how to solve it :-D, but I suspect that there is a standard solution which is more elegant. So, here is my problem: I have django app versioned with svn and I test my trunk on two different machines (one with mysql, another with sqlite3). How do I remove database-definition constants from my settings.py and put them in a separate file which wouldn't be maintained by svn? (did I really hear somebody call that kind of file unversioned file or did I make that up?) I suppose I could make a trivial module with database info, import it and then assign my constants with data from that module, but that looks so unelegant to me.

Normally you wouldn't do that unless you were trying to debug the
interpreter itself. It uses caught exceptions for all sorts of things
that you probably don't want displayed. I think even ordinary loop
termination may be implemented using exceptions.
Yes, thanks for your quick responses, all three. You're right, I don't
want to debug python :-) But I figured out that I don't need captured
exceptions, the thing is that I just didn't belive the problem was that
obvious. In fact, problem was in the except block, not in it's try
block. The except block had this inocent statement:
