Submit the form causing the errors with unicode characters (e.g.é) in it! This is a very common error in Django projects and it almost always means you are calling str() somewhere. Django uses unicode strings internally but when you call str() you are asking Python to give you an ascii string back, which fails with th...

Use Timer instead of signals. Dealing with signals will open up lots of cans of worms, so you should avoid it whenever you can. In this case, it sounds like you can.

Python can store arbitrarily long integers using the long type and even lets you specify long literals by appending an L to them (e.g. 0L is a long zero, as opposed to just 0 which is an int). Even better, it automatically "promotes" numbers from ints to longs when the result of a calculation is too large to be represe...

I'm planning to use very big numbers in Python, but wonder if Python can handle very big numbers. The numbers are going to have up to 3,000 zeros. And, how much bytes does a 1 with 3,000 zeros use? Third question, how can I save a number as integer into a file with Python without having to str() it?

In the example you post, line length suffices. There is no perfect algorithm; even human beings will classify lines differently. I suggest just use line length until you find a counter example, at which point revise your algorithm. Repeat until problem solved to your satisfaction.

put your script in a new folder. run the 1st script (configure.py if memory serves) run the 2nd script (make.py yourfolder\yourscript.py again from memory) run the last script(build.py yourfolder\yourscript.spec) you should have an exe now. good luck.

If you have pyinstaller set in your path variable, as I do, all you have to do is: pyinstaller -F And it automatically generates everything else.

Roundcube have this in both the server and user configuration. I don't know about other mail clients, but I guess they either use heuretics, either by just looking at what folders there are or by using knowledge about the particular IMAP server.

Yes, OCaml is suitable for concurrent programming. It does have a Thread module that allows you to program network applications the way you would do it in Java. Note that it currently does not support true parallelism (you won't have two threads running OCaml code in parallel), but it doesn't matter as OCaml is much fa...

I have done some Java programming and very little C and PHP programming as well. Recently I started to learn Python because the language seemed interesting. But several posts on SO seemed to point that Python is not suitable for concurrent programming. And also is slower compared to those languages that have a compiler...

There's no need to wrap the context processor. If you've wrapped the view in the first place, then the request will already be annotated with the facebook.user attribute. Since the request is passed to the context processor anyway, you have access to that attribute. You should probably do a quick check - if hasattr(req...

I'm using Fandjango for a Django Facebook Canvas app. To use fandjango, you need to wrap all view functions with @facebook_authorization_required, which makes sure you're authorized, then gives you the variable request.facebook.user. What I want is to make a context processor which defines a few more variables based on...

Since you created the API console project with an Apps account (one @yourdomain.com), the project is automatically treated as an Apps project, and only users from your domain can be added to it. To avoid this, create a new project using a @gmail.com account, and then add all the developers you want to have access to it...

I try to enable Cloud Storage for my GAE app. I read in the docs that: Add the service account as a project editor to the Google APIs Console project that the bucket belongs to. For information about permissions in Cloud Storage, see Scopes and Permissions on the Cloud Storage documentation. However when I try ...

I have inherited a number of javascript files containing a mixture of JSON objects and other js declarations (functions, variables). I'm writing a python script to move the data contained in the JSON objects into another system. I'd like to avoid duplicating any sort of parser functionality in what is essentially a th...

A few ideas: Ad-hoc & approximate: The "2-D histogram". Create arbitrary "rectangular" bins, of the degree width of your choice, assign each bin an ID. Placing a point in a bin means "associate the point with the ID of the bin". Upon each add to a bin, ask the bin how many points it has. Downside: doesn't correctly...

If I am using a python script with mechanize to fill out forms on websites (such as login information) should I be worried about encryption?

So I'm looking to take input such as 7:00 AM as a start time, and say, 10:00 PM as an endtime, and then compare a set of times (also in the form of 8:00 AM, 3:00 PM, etc) to see if those time are or aren't in the range of time. Is there a good way to create a "day" that has a range of hours (the endtimes can be as late...

My friend's response is below, pardon the language please. First I wrote up a Python implementation of the collapsed Gibbs sampler seen here (http://www.pnas.org/content/101/suppl.1/5228.full.pdf+html) and fleshed out here (http://cxwangyi.files.wordpress.com/2012/01/llt.pdf). This was slow as balls. Then I used a Pyt...

Wrapper Write functions in the native language whose sole purpose is to call the functions in the external library. The goal is to do as little as possible in the native language. For example, translating data types from the native language to the external library language, etc. Wrappers make sense when the external ...

Types defined in C can never have user-assigned attributes. If you want to replace object globally then you'll need to iterate over every single class in existence, then replace __builtin__.object to catch all future class creation. And even that isn't reliable since the old object could be bound somewhere else.

Every class in python inherits from the class 'object.' I am wondering about the internal mechanism of the 'object' class implementation. Why cannot the 'object' class be assigned any user-attributes? I am convinced that it is related to memory-management but what if the user thinks of implementing the memory-managemen...

In general, dependencies should be a tree. Circular dependencies are not resolvable. The usual way to solve this, though, is to do a "local import" of the required module at a level other than the global namespace.

this is a case again where I'm running around in circles and I'm about to go wild. I wish Python would analyze all files at first, so that it would know all identifiers from the beginning (I think like Java does). I have a "main.py" and a "gui.py". Every file contains a class, that makes use of the class in the other f...
