Hi, I am using Python 2.5.1 I have an application that reads a file and generates a key in a dictionary for each line it reads. I have managed to read a 1GB file and generate more than 8 million keys on an Windows XP machine with only 1GB of memory and all works as expected. When I use the same program on a Windows 2003 Server with 2GB of...

I'm using deepcopy in some code which eventually ends up by crash witht he following rather long winded error. I'm not directly using _hashlib.HASH, but I suppose something else along the way could be. Is there some nice way to make copy/deepcopy give more information when this error happens? I know what the top level object is, but presumably...

Hi, I'm using the Image module to resize PNG images from 300 to 100dpi for use in HTML pages, but I'm losing some vertical and horizontal lines in the images (usually images of x-y plots). Here's what I do: import Image def imgResize(self,filename): img = Image.open(filename) dpi = img.info.get('dpi') if dpi and 295 < int(dpi) < 305:

Hello, I've been playing with the python logging module lately, and I manage to log to both stderr and MySQL database. What I'm wondering, is if its possible to specify the database handler in a config file like: class=DBHandler

Hi, CGIHTTPServer does not support redirects Is there an other python-only way to get a web server running wich can execute python code? Since I already use flup. I think there is not much missing to get it serving as http server.

I have just come across a site that discusses Python's 'for' and 'while' loops as having an (optional) 'else' structure. At first glance I interpreted it as being a bit like the 'default' structure in PHP's switch block... But the switch block isn't a loop, so, I am now confused as to the reason for using 'else' with the for and while...

Hi. I've got a question on the differences and how to define static and class variables. AFAIK, class methods are the ones which receives the class itself as an argument, while static methods are the one which runs statically with the defining class. Hence, my understanding is that static variables must be bound to the class defining the...

Hello group, I'm writing a C++ based application that embeds the python engine. Now I have a problem regarding exception/error information. Is there a way to get the exception message and possibly the traceback into a string for example? I've been eyeballing the PyErr_ module and it seems fairly limited. In other words PyErr_Print() calls...

Hello, I have several servers which link to each other (and of course, to clients). At present, I am starting them in turn manually. Is there a way with python to say, "open gateway.py in a new interpreter window"? I looked at execv, etc, but they seem to replace the current process. Ah, maybe I need spawnv().
