What for a file that prints nothing

[sylas]

Hi all ! I have this file that prints nothing. How to modify in order to see something ??

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

class _Getch:     """Gets a single character from standard input.  Does not echo to the screen."""     def __init__(self):         try:             self.impl = _GetchWindows()         except ImportError:             self.impl = _GetchUnix()       def __call__(self): return self.impl()     class _GetchUnix:     def __init__(self):         import tty, sys       def __call__(self):         import sys, tty, termios         fd = sys.stdin.fileno()         old_settings = termios.tcgetattr(fd)         try:             tty.setraw(sys.stdin.fileno())             ch = sys.stdin.read(1)         finally:             termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)         return ch     class _GetchWindows:     def __init__(self):         import msvcrt       def __call__(self):         import msvcrt         return msvcrt.getch()     getch = _Getch()#origin #char = getch.getche() # also displayed on the screen #char = _Getch() # also displayed on the screen

That's a pretty old library, and doesn't work on macOS (just tried it). You might want to look at a more recent alternative (which I think might be based on the ActiveState recipe you shared).

readchar 2.0.1 on PyPi

I tried it in the shell, and it worked fine with this code:

1 2 3 4

import readchar while True:     key = readchar.readkey()     if key == " ": break

Obviously, I could print whatever character was read (assuming it was printable character).
