Django has a number of open source projects that tackle one of the framework's more notable missing features: model "evolution".

Hi, I am looking for a way to represent '\n' with only one character. I am writing a program that uses dictionaries to 'encrypt' text. Because each character is represented in the dictionary, i am having a problem when my program gets to a '\n' in a string, but reads it as '\' 'n' . Is there alternate way to represent a newline, that is ...
I was bored and playing around with the ipython console and came upon the following behaviour I don't really understand In [1]: 2**2 Out[1]: 4 In [2]: 2**2**2 Out[2]: 16 In [3]: 2**2**2**2 Out[3]: 65536 In [4]: 2**2**2**2**2 The answer to [4] is not 4294967296L, it's a very long number, but I can't really figure out why. The numbe...
I am working on a Django application which allows a user to upload files. I need to perform some server-side processing on these files before sending them on to Amazon S3. After reading the responses to this question and this blog post I decided that the best manner in which to handle this is to have my view handler invoke a method on ...

For example: testDict={'x':2,'xS':4} def newFunct(key,testDict['key']): newvalue=key+str(testDict['key']) return newValue for key in testDict: newValue=newFunct(key,testDict[key]) print newValue I get a SyntaxError: invalid sy...
It seems that all roads lead to having to use PyISAPIe to get Django running on IIS6. This becomes a problem for us because it appears you need separate application pools per PyISAPIe/Django instance which is something we'd prefer not to do. Does anyone have any advice/guidance, or can share their experiences (particularly in a shared W...

Is there any way, in Python, to "programmatically" (:-) change the CAPS LOCK/NUM LOCK/SCROLL LOCK states. This isn't really a joke question - more like a real question for a joke program. I intend to use it for making the lights do funny things ;-) ...
I recently wrote a program that used a simple producer/consumer pattern. It initially had a bug related to improper use of threading.Lock that I eventually fixed. But it made me think whether it's possible to implement producer/consumer pattern in a lockless manner. Requirements in my case were simple: One producer thread. One consume...
