Using msvcrt.getch () in Eclipse / PyDev

Question

I wanted to use msvcrt.getch() in Eclipse with PyDev to read signe char, but I found out that it just doesn't work (but it works on the Windows console).

Any idea what to do?

Answer 1

Maybe use sys.stdin.read when starting up in PyDev? for example, sys.stdin.read(1) read 1 line from the input ... For use in the Windows console and PyDev, make the same choice based on the os and run options (using sys.stdin.isatty ). For example, the following code reads user input. But when launched in the Windows console, if the standard input code of the program is connected to another software standard, then sys.stdin.isatty returns False and enters reading using sys.stdin.read , and not msvcrt.getch :

 import sys, time import platform if platform.system() == "Windows": import msvcrt else: from select import select def input_with_timeout_sane(prompt, timeout, default): """Read an input from the user or timeout""" print prompt, sys.stdout.flush() rlist, _, _ = select([sys.stdin], [], [], timeout) if rlist: s = sys.stdin.readline().replace('\n','') else: s = default print s return s def input_with_timeout_windows(prompt, timeout, default): start_time = time.time() print prompt, sys.stdout.flush() input = '' read_f=msvcrt.getche input_check=msvcrt.kbhit if not sys.stdin.isatty( ): read_f=lambda:sys.stdin.read(1) input_check=lambda:True while True: if input_check(): chr_or_str = read_f() try: if ord(chr_or_str) == 13: # enter_key break elif ord(chr_or_str) >= 32: #space_char input += chr_or_str except: input=chr_or_str break #read line,not char... if len(input) == 0 and (time.time() - start_time) > timeout: break if len(input) > 0: return input else: return default def input_with_timeout(prompt, timeout, default=''): if platform.system() == "Windows": return input_with_timeout_windows(prompt, timeout, default) else: return input_with_timeout_sane(prompt, timeout, default) print "\nAnswer is:"+input_with_timeout("test?",10,"no input entered")
