However, if the scrollbar thumb is positioned somewhere else, I want the view to stay fixed at that spot . . . I understand things chan...
This PHP code below fetches html from server A to server B. I did this to circumvent the same-domain policy of browsers. (jQuery's JSONP can also be used to achieve this but I prefer this method) <?php /* This code goes inside the body tag of server-B.com. Server-A.com then returns a set of form tags to be echoed in the body tag...

After we write a code in Matlab we can use ctrl+A+ctrl+I and ctrl+A+ctrl+J to format our code (comments, loops alignment etc). Is there something similar or any helpful keyboard shortcuts in Python? Also, just like we can use upward arrow to copy our previous command window history in Matlab, is it possible or some keyboard shortcut to ...
I'm working in Linux and am wondering how to have python tell whether it is being run directly from a terminal or via a GUI (like alt-F2) where output will need to be sent to a window rather than stdout which will appear in a terminal. In bash, this done by: if [ -t 0 ] ; then echo "I'm in a terminal" else zenity --info --tit...
lets say i have arrays: a = array((1,2,3,4,5)) indices = array((1,1,1,1)) and i perform operation: a[indices] += 1 the result is array([1, 3, 3, 4, 5]) in other words, the duplicates in indices are ignored if I wanted the duplicates not to be ignored, resulting in: array([1, 6, 3, 4, 5]) how would I go about this? the examp...

I'm having an issue with blobstore uploads, but because of the way gae handles all of that, actually figuring out what the error was is giving me some trouble. I'm using django, which unfortunately tries very hard to prevent exceptions from reaching the user without formatting. It looks like the uploads are successful, there are __Blob...
I have two classes. They're almost identical, except for 2 attributes. I need to copy all the attributes over from one to the other, and I'm just wondering if there is a pattern or best practice, or if I should just basically do: spam.attribute_one = foo.attribute_one spam.attribute_two = foo.attribute_two ... and so on. ...
Dear All, In using the numpy.darray, I met a memory overflow problem due to the size of data，for example: Suppose I have a 100000000 * 100000000 * 100000000 float64 array data source, when I want to read data and process it in memory with np. It will raise a Memoray Error because it works out all memory for storing such a big array in ...

I'm working on a toy language, and I've implemented the ability to stream lines of text from shell commands lazily (as a generator).

I have a 2-d array xx=[[a,1],[b,2],[c,3]] Now I'm trying to remove duplicate entries from it. For simple 1-D array, simple code like xx=list(set(xx)) would work. But trying set on 2-d elements gives an error temp = set(xx) TypeError: unhashable type: 'list' One workaround would be to serialize xx elements, and then do a list(se...
