问题 I'm trying to retrieve the coordinates of cursor in a VT100 terminal using the following code: void getCursor(int* x, int* y) { printf("\033[6n"); scanf("\033[%d;%dR", x, y); } I'm using the following ANSI escape sequence: Device Status Report - ESC[6n Reports the cursor position to the application as (as though typed at the keyboard) ESC[n;mR, where n is the row and m is the column.

You could get

问题 How can I permanently change the PYTHONPATH on a mac? I've tried editing .bash_profile, but when I use print sys.path in a file it gives a huge list of different URLs than the .bash_profile.
