I am using a module that is part of a commercial software API. The good news is there is a python module - the bad news is that its pretty unpythonic. To iterate over rows, the follwoing syntax is used: cursor = gp.getcursor(table) row = cursor.next() while row: #do something with row row = cursor.next() What is the most ...
Hi, i have a large dictionary I'd like to save. I have pickled it using cPickle.dumps and saved the result into a TextField. When trying to retrieve it (cPicle.loads) i get the following error: loads() argument 1 must be string, not unicode Does anybody have any experience in serializing python objects and storing them in a DB using D...
Is it possible to change or assign new parent to the Model instance that already in datastore? For example I need something like this task = db.get(db.Key(task_key)) project = db.get(db.Key(project_key)) task.parent = project task.put() but it doesn't works this way because task.parent is built-in method. I was thinking about creating...
Hi all, I need to make a variable with similar behaviour like in C lanquage. I need byte or unsigned char with range 0-255. This variable should overflow, that means... myVar = 255 myVar += 1 print myVar #!!myVar = 0!! ...
I didn't think this would be as tricky as it turned out to be, but here I am. I'm trying to write a Nautilus script in Python to upload one or more images to Imgur just by selecting and right clicking them. It works well enough with both single images and multiple images - as long as they don't contain any whitespace. In fact, you can up...
I am writing an app to do a file conversion and part of that is replacing old account numbers with a new account numbers. Right now I have a CSV file mapping the old and new account numbers with around 30K records. I read this in and store it as dict and when writing the new file grab the new account from the dict by key. My question i...

I thought I'd put together a quick script to consolidate the CSS rules I have distributed across multiple CSS files, then I can minify it. I'm new to Python but figured this would be a good exercise to try a new language. My main loop isn't parsing the CSS as I thought it would. I populate a list with selectors parsed from the CSS file...
I have a Python module, wrapper.py, that wraps a C DLL. The DLL lies in the same folder as the module. Therefore, I use the following code to load it: myDll = ctypes.CDLL("MyCDLL.dll") This works if I execute wrapper.py from its own folder. If, however, I run it from elsewhere, it fails. That's because ctypes computes the path relativ...

Hi, I need to write a program to scrape forums. Should I write the program in Python using the Scrapy framework or should I use Php cURL? Also is there a Php equivalent to Scrapy? Thanks ...
Dear All .. I'm learning to drive a stepper motor with Python. It's hard now to find a PC with paralel port. So My plan is using a USB-Serial .. and a SIPO (serial in parallel out) shift register circuit. As you know with this circuit we need to send a binary data in series and this data will be stored in it's register. Next we need to...
I'd like convert strings to floats using Python 2.6 and later, but without silently converting things like 'NaN' and 'Inf' to float objects. I do want them to be silently ignored, as with any text that isn't valid as a float representation. Before 2.6, float("NaN") would raise a ValueError on Windows. Now it returns a float for which ...
I am trying to host some files/rails app in the port 8080 for external access. For python I am using the SimpleHTTPServer module, and for rails, webrick. However, both of them does not work very well. I don't get the response back, and, sometimes, if I get it, it's VERY slow. Nevertheless, apache works very well on the port 8080 (i am no...
Using python and wsgiref.handlers, I can get a single variable from a form with self.handler.request.get(var_name), but how do I iterate through all form variables, be they from GET and POST? Is it something like this? for field in self.handler.request.fields: value = self.handler.request.get(field) Again, it should include both fi...

Hi, i just finish some MYSQL to excel script with xlwt and I need to colour every second row for easy reading. I have tried this: row = easyxf('pattern: pattern solid, fore_colour blue') for i in range(0,10,2): ws0.row(i).set_style(row) Alone this colouring is fine, but when when I write my data rows are again white. Can some ple...
I've been trying to find a good and flexible way to parse CSV files in Python but none of the standard options seem to fit the bill. I am tempted to write my own but I think that some combination of what exists in numpy/scipy and the csv module can do what I need, and so I don't want to reinvent the wheel. I'd like the standard feature...
The GeoDjango tutorial explains how to insert world borders into a spatial database. I would like to create a world Map in HTML with these data, with both map and area tags. Something like that. I just don't know how to retrieve the coordinates for each country (required for the area's coords attribute). from world.models import World...
