So i need a efficient way to do it . And it's better to reshape it in-place. 回答1: As proposed by @atomh33ls, you can use a reshape passing order='F' , and "if possible" the returned array will be only a view of the original one, without data being copied, for example: a = array ([ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]) b = a

Example 1 - Shellcode in C program Example 2 - http://www.debasish.in/2012/04/execute-shellcode-using-python.html All methods have broadly similar techniques - assign the shellcode to executable memory via the OS specific allocation (mmap, virtualalloc, etc) and then execute the code by creating a function pointer pointing to that location before executing. Here is my horrible hacky example at performing the same thing in Go. The

Thanks for your help. 回答1: The problem is that you're modifying the array while jQuery's $.each is looping over it, so by the time it gets to

Now, I am getting "Range Check Error." I have spent hours researching online about this, but none of them seem to give me what I am looking for. My program was complied with the Runtime Error option Range Check. So, I know that's why I am getting the error, but I needed to know exactly why the error is raised. The program was compiled on XP with Delphi 7.0. The testing PC is a Windows 7. As soon as it starts
