An example of what I would like to do is the following:
import curses
while True:
key = stdscr.getch()
if key == 119:
print("key w pressed")
else:
print("w key not pressed")
Where the else statement prints constantly, not only when a key is entered and getch does not return 119. In other words, I don't want the getch function to wait for a key press, I only want it to only return a key if a key is being pressed, otherwise return None or something like that.
In curses the window has a nodelay
flag. If it is set to true, the getch function won't wait for user input, but will return -1
if no input is to be read.
import curses
stdscr.nodelay(True)
while True:
key = stdscr.getch()
if key == -1:
print("no key was pressed")
elif key == 119:
print("key w pressed")
else:
print("different key than w was pressed")
