Hi. Suppose we have a very large file, and wanna remove 'n' bytes in the middle of the file. My thought is: 1, read() until we reach the bytes should be removed, and mark the position as 'pos'. 2, seek(tell() + n) bytes 3, read() until we reach the end of the file, into a variable, say 'a' 4, seek(pos) back to 'pos' 5, write(a) 6, truncate()
If the file is really large, the performance may be a problem. Is there a clever way to finish? Could mmap() help? Thx -- http://mail.python.org/mailman/listinfo/python-list
