This link contains a python code example about how to initialize the memory, set bytes in this memory and how to copy these bytes to another destination.

 You can control two things, the bytes to any string you want to be added to this memory and the first parameter in the third function (memcpy) in the code , you can put the destination of where this string will be copied.

Thank you anyway,

unfortunately,that did not work with me,because I need a python code that uses CopyMemory API,so this is  was not what I need.
