I have to know what key is pressed, but not need the code of the Character, i want to know when someone press the 'A' key even if the key obtained is 'a' or 'A', and so with all other keys.
I can't use PyGame or any other library (including Tkinter). Only Python Standard Library. And this have to be done in a terminal, not a graphical interface.
NOT NEED THE CHARACTER CODE. I NEED TO KNOW THE KEY CODE.
ord('a') != ord('A') # 97 != 65
someFunction('a') == someFunction('A') # a_code == A_code
See tty standard module. It allows switching from default line-oriented (cooked) mode into char-oriented (cbreak) mode with tty.setcbreak(sys.stdin). Reading single char from sys.stdin will result into next pressed keyboard key (if it generates code):
import sys import tty tty.setcbreak(sys.stdin) while True: print ord(sys.stdin.read(1))
Note: solution is Unix (including Linux) only.
Edit 2: Utilize win32 low-level console API via ctypes.windll (see example at SO) with
ReadConsoleInput function. You should filter out keypresses -
e.EventType==KEY_EVENT and look for
e.Event.KeyEvent.wVirtualKeyCode value. Example of application (not in Python, just to get an idea) can be found at http://www.benryves.com/tutorials/?t=winconsole&c=4.
