I'm using Pycharm on unix. I'm trying to read a single character (like 'y' or 'n') from the console. It runs fine, when I execute it on the command line, but when I'm running the program inside Pycharm I get the following error:

termios.error: (25, 'Inappropriate ioctl for device')

I know, that the ide is not a tty, but I haven't found a workaround.

This is my function (seems to be pretty standard) to read the character. 

def getch():
    import sys, tty, termios
    fd = sys.stdin.fileno()

    old_settings = termios.tcgetattr(fd)
    try:
        tty.setraw(fd)
        ch = sys.stdin.read(1)
    finally:
        termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)
    return ch

while True:
    char = getch()
    if char == 'q':
        exit()
    else:
        print char

  • Did you ever solve this? I am trying to help someone who is getting the same error on OSX for getch(). Commented Sep 2, 2015 at 7:07

    No, I didn't find any solution. I just defined a force (s.th. like --f) command-line argument with argparse as a workaround, which works for most of my use cases. Commented Sep 2, 2015 at 8:00
