title: How use curses.raw() and curses.cbreak()
body: <p>So first I want to capture the keys (w,a,s,d) when are pressed.
  And I think with curses I can make it, but I am new using python, and I need help, How capture the key pressed in the keyboard. I try with a input but I need touch enter to change, but in my program I don't need pressing enter. I just need when I press, for example w do something without pressing enter.</p>
