I have a scrapy project that I would like to package all together for a customer using windows without having to manually install dependencies for them. I came across cxfreeze, but I'm not quite sure how it would work with a scrapy project. I'm thinking I would make some sort of interface and run the scrapy crawler with 'from scrapy.cmd...

As a general rule, I rue the days whenever I have to build Python libraries on a Mac. I've generally had fairly good success using Boost::Python, and if I use distutils, most of the time everything works correctly. However, I've never been able figure out the exact combination of what works/what doesn't work. Specifically, I've often ru...
Consider this Python code: assert(a > 0) assert(b > 0) assert(a + b > 0) Can the third assert ever fail? In C/C++, it can if the sum overflows the maximum integer value. How is this handled in Python? ...
I'm using python to manage some simulations. I build the parameters and run the program using: pipe = open('/dev/null', 'w') pid = subprocess.Popen(shlex.split(command), stdout=pipe, stderr=pipe) My code handles different signal. Ctrl+C will stop the simulation, ask if I want to save, and exit gracefully. I have other signal handlers ...
Let's say I have a list of colours, colours = ['red', 'blue', 'green', 'purple']. I then wish to call this python function that I hope exists, random_object = random_choice(colours). Now, if random_object holds 'blue', I hope colours = ['red', 'green', 'purple']. Does such a function exist in python? ...
I need to make some command line calls to linux and get the return from this, however doing it as below is just returning 0 when it should return a time value, like 00:08:19, I am testing the exact same call in regular command line and it returns the time value 00:08:19 so I am confused as to what I am doing wrong as I thought this was h...

Once they are signed in and leave the web app homepage a horizontal GUI bar will appear on each page th...
It seems that an acceptable answer to the question What is a method? is A method is a function that's a member of a class. I disagree with this. class Foo(object): pass def func(): pass Foo.func = func f = Foo() print "fine so far" try: f.func() except TypeError: print "whoops! func must not be a metho...
basically the problem is, that the only way to get all instances of VLC is to search all non-named instances for the org.freedesktop.MediaPlayer identity function and call it. (alternatively I could use the introspection API, but this wouldn't seem to solve my problem) Unfortunately many programs upon having sent a dbus call, simply do ...
I am working on a chatroom client and am using an HTML window to process things like images and html tags and formatting. I am having trouble finding out how to make the scrollbar stay at the bottom as messages are added to the window (every message sends the bar to the top) would anyone know how I would go about doing this? ...
I'm at a point in my Pylons projects where I end up creating and deleting controllers often (probably more often than I should). I grow tired of adding my own imports and tweaks to the top of every controller. There was a recent question about modifying the new controller template that got me part-way to not having to do that - but I do...

I'm using a script that someone else wrote in python. It's executed from the command line with 3 arguments. example: "python script.py 1111 2222 3333" It does it's thing and works perfectly. The results are NOT saved though, and I would really like to pipe the output to a text file. Can I simply use similar dos commands to accomplis...
Standard streams are associated with a program. So, suppose there is a program already running in some way (I don't care how or in what way). The goal is to create pipes to the STDIN of the program from different processes (or programs) that run either locally or remotely and stream data into it asynchronously. Available information is ...

I want to build a system using Django that will allow users to build forms, store them and have their customers use them. I know how I can go about creating the forms dynamically but I'm looking for a good way to still use the form classes and handle many different user's dynamic forms in an elegant way. I'm thinking of storing the for...
