I'm writing a little program as a self-learning project in Python 3.x. My idea is for the program to allow two fields of text entry to the user, and then plug the user's input into the value of two specific registry keys. Is there a simple way to make it check if the current user can access the registry? I'd rather it cleanly tell the u...
In a unit test case that I am running, I get a KeyError exception on the 4th json object in the json text below because the piece of code responsible for decoding is looking for an object that isn't there, but should be. I went through the sub-objects and found that it was the "cpuid" object that causes the problem. When I remove it ...

I guess the question speaks for itself. I'm interested in doing some serious computations but am not a programmer by trade. I can string enough python together to get done what I want. But can I write a program in python and have the GPU execute it using CUDA? Or do I have to use some mix of python and C? The examples on Klockner's ...
I've been reading up a lot lately on comparisons between Python and a bunch of the more traditional professional languages - C, C++, Java, etc, mainly trying to find out if its as good as those would be for my own purposes. I can't get this thought out of my head that it isn't good for 'real' programming tasks beyond automation and macro...
Lets say that we are getting POSTed a form like this in Django: rate=10 items= [23,12,31,52,83,34] The items are primary keys of an Item model. I have a bunch of business logic that will run and create more items based on this data, the results of some db lookups, and some business logic. I want to put that logic into a save signal or...

I'm making a small script in python with ttk and I have a problem where a function runs where it shouldn't. The button code looks as follows: btReload = ttk.Button(treeBottomUI, text="Reload", width=17, command=loadModelTree(treeModel)) btReload.pack(side="left") and the function is as this: def loadModelTree(tree): print ("Loa...
I was instructed to prevent this from happening in a Python program but frankly I have no idea how this is even possible. Can someone give an example of how you can slice a list and insert something into it to make it bigger? Thanks ...
Hi. I am trying to use optparse but I am having a problem. My script usage would be: script <filename> I don't intend to add any option string, such as: script -f <filename> or script --file <filename> Is there any way I can choose not to pass an argument string? Or is there any way I can allow the user to do this: script -f <filena...

I know about the LEGB rule. But a simple test of whether a function has read access to variables defined in an enclosing function doesn't seem to actually work. Ie: #!/usr/bin/env python2.4 '''Simple test of Python scoping rules''' def myfunction(): print 'Hope this works: '+myvariable def enclosing(): myvariable = 'ooh this w...
Ok, here is the question. Imagine I have a ModelForm which have only two fields. like this one: class ColorForm(forms.Form): color_by_name = forms.CharField() color = forms.IntegerField(widget = forms.Select(choices=COLOR_CHOICES)) So a user can either input a color name, a choose it from a list. Color is required, but that ...
In the google documentation it shows storing cursors in memcache, however as pointed out in an answer to this question memcache retention isn't guaranteed. So I was wondering how other people store cursors and what strategies you use for handling missing cursors? ...

Obviously I can do this by overriding the save method, but I am wondering if...
