Return from C extension throws segmentation fault
Hi all,
I have been making a C extension to Python recently. This extension has a function that takes a 3D array (as made by pygame.surfarra y.pixels3d), is going to do operations on this array, and then return it.
My problem is, that the most basic form of this function is throwing a segmentation fault after 58 calls from my program. The input is always a 3D array of integers, 1st dimension of size 70, second of size... -

Reading from array into the file - with encoding ascii characters
Dear members,
I'm a newbie and I created a simple program, but I have one problem I can't deal with. I should work on Win CE.
Ok: I want this program to read 'array of arrays' and save encoded data into file.txt. Every 3 bytes from there should be encoded from ASCII (function below).
The biggest problem is with loop (or some other way to fix it) to read all array (without any skips).
Now it's like:... -

How to transfer a 2d array into a table
I have a 2d array, with 10 columns, and somewhere between 200 and 10.000 rows. I was hoping there was a simple(and efficient) way to transfer the entire array into a table containing over a million rows, and growing.
I allready know how to transfer it by looping through the array, adding 1 row at a time. However, this is not that effective, and I believe that one of the problems stems from the fact that the main table has its indexes... -
