Okay, next problem: pygame. The book I'm using uses pygame and some other package, but I cannot for the life of me to get Pygame to install. At first, it throws the error that it doesn't exist, when I move the files over to the proper folder, I get this: pre:Traceback (most recent call last):

What is the best way to read a null-terminated string from a socket? Right now I'm looping on recv(1). I know I could do larger reads, but the stuff after the null-terminated string needs to be read by something else. Is recv(1) the only/best way?

There might already be something like this in the standard library; if not, it's very easy to write.

Grabulon posted:And I won't have any issues with the built-in Python? I'm assuming your path is pointing to that Python and you should be able to edit it to point to the new one or put 2.7 in front of it. I'm assuming it appends itself to the path at the rear. You are able to have multiple versions of python installed and you can call whichever one you want to run whatever python file you have. So you'd be able to install 2.5 and 2.7 and not have any issues, as long as you know which one is being executed.

If I needed 2.7 specifically (I don't, and just use the default system python + virtualenv), I'd use Homebrew's python package; Homebrew is completely distinct from the rest of the system, so it'd be quite easy to nuke/modify the Homebrew-installed version later without accidentally screwing up the built-in system Python. All you need to do is ensure that `/usr/local` is on your path (eg `/usr/local/bin`, etc -- Homebrew install should make that all clear) and anything you install via Homebrew will take precedence over (but not replace or modify!) any builtin stuff.

IDLE or just using running python from the command line are really good for hacking away when first getting started to understand the basic datatypes, how to call methods etc. As soon as you start writing your own classes or basically doing any real programming, I would recommend avoiding IDLE. I personally use VIM but IMHO anything is better than IDLE.

A lot of the features of a good programming environment (Can't remember the term off the top of my head) didn't make sense until you actually know the code. Modern Pragmatist posted:IDLE or just using running python from the command line are really good for hacking away when first getting started to understand the basic datatypes, how to call methods etc. As soon as you start writing your own classes or basically doing any real programming, I would recommend avoiding IDLE. I personally use VIM but IMHO anything is better than IDLE. These are both good pieces of advice. I'll add in that even once you start doing fancier stuff, IDLE and the python command shell are great as REPLs to quickly test out very small ideas before you include them in your bigger project. As for which IDE to switch to once you're a bit more comfortable with the language, I'm a fan of JetBrains' PyCharm. I think it's the best mix of intuitiveness and powerful features I've seen in a Python IDE. PyDev is another common suggestion, and it's not too bad, but I found it to be slightly clunkier and significantly worse at things like code completion than PyCharm. That said, it is totally free - PyCharm isn't (unless you're using it for a class or an "active" open source project). Vim and Emacs also tend to come up when people ask this question. They're both extremely powerful and are really useful tools to be familiar with, and once you become good at using them they are both extremely efficient. That said, they also both have pretty steep learning curves and tend to require a lot of customization to bring them from "good" to "extremely effective". I'd say that either of their learning curves is significantly steeper than Python's itself, and would probably avoid them until/unless you find yourself wanting more than something like PyCharm or PyDev can offer. e: vvvvvvvvvvvvvvvv I totally forgot about Pyscripter, but I used that before I tried PyCharm and thought it was slightly better than PyDev. Still not as good as PyCharm. brosmike fucked around with this message at 04:12 on May 23, 2011 |

When it gets to the point you're considering an IDE, I can't say enough great things about Pycharm (it's unfortunately not free, but there's 30 day free trial and free licensing for academics and Open Source developers) Also, for free stuff, I liked: - Pyscripter (windows only) - SPE I think that Pydev/eclipse is fine, but if you're not coming from a Java background (like me) the normal way Eclipse does things just isn't intuitive. for the emacs/vi crowd, my opinion is: if you already know it, go right ahead, otherwise, there's a lot more to be gained from purpose-built tools for python editing.

Only thing I could suggest would be to use the actual logging module. That way you can just redirect it at will. Plus it makes things look cleaner in the long run. That being said, it's a good idea and I like the simple implementation.

I've got an idea for a project bouncing around in my head, but there's one thing I don't know how to do... Say I create a Django-based app that lets an end-user store stuff in a db. The db has several tables. Now, lets say I'm going to host this application and people create accounts and each person stores their own stuff. Basically like how a bajillion other websites work...you create an account and stuff is tied to your account. The thing I'm confused about is how you handle the multiple accounts. In a single-user scenario the end user would have several tables in the db, but it definitely seems inefficient to have the hundreds of millions of users of my super awesome application each having several tables of their own. How do I design such a thing?

Thermopyle posted:I've got an idea for a project bouncing around in my head, but there's one thing I don't know how to do... The answer to your question has nothing to do with Django or Python, it's basic database theory. You need to create tables that can be reused by multiple users, not create the same table with the same structure for each new user that joins. Each row in these tables would have a foreign key back to the user table, so you know who that row belongs to.

I'm trying to install Python 2.6, and I'm getting this error: I get that whether C:\\python26 exists before I start the install or not. I'm using Windows 7 so this might be part of that bug which prevents you from turning off "read-only". I want an older version of Python because I need NLTK. Should I just install 2.5, or is there a work-around here?

what do you guys think of this:pre:def bar():

return None.x
class A(object):
@property
def foo(self):
return bar()
def __getattr__(self, a):
print 'attribute %s not found' % (a,)
A().foo
hoi attribute foo not found it seems like __getattribute__ is interpreting the AttributeError raised in bar() as a failed lookup for foo and calling __getattr__, which in theory shouldn't happen.

Okay, so, directly quoting my Stack Overflow post because I have to solve this or I can't keep working: Basically, I'm trying to get Django to simply allow me to use Twitter information as login/logout information, basing all of the accounts of my system off of Twitter accounts. Twitter and oauth are working wonderfully- Django isn't. I'm constantly getting the following error: Getting a 'AttributeError at /login/authenticated', 'User' object has no attribute 'backend' From the research I've done, this tends to come across when you try to skip your call to authenticate(), which leads me to thinking that somehow that call is failing somehow, but it isn't telling me so. This is vaguely confirmed by the fact that I don't get the error at all, and get sent straight through, when I comment out the login line. The code in question: code:

quaunaut posted:Any ideas why that authenticate could be failing? I'm open to anything, and showing you absolutely any of my code(save my settings.py file unedited, of course). The oauth library I'm using is here. Unlikely, but are you using a custom value for AUTHENTICATION_BACKENDS in your settings.py? Failing that, I'd say your best bet is to put a breakpoint on the authenticate() call and step through that - a cursory glance at its source code suggests that something pretty weird is happening if it's not returning None but also not setting the backend attribute.

When you access a property, it runs the method. If an AttributeError is raised within that method, it is caught and then __getattr__ is called.
