msvcrt.hbhit() and msvcrt.getch() in Wing Pro 8 on Windows 10

edit

Hi, I am using Wing Pro 8 on Windows 10. My Python scripts use mscvrt package for hbhit() and getch(). I can get input characters without them being printed on the screen. They work fine in Windows Command window be behave differently in Wing Pro 8. Here is a test script:

import msvcrt
import time
while True:
  while msvcrt.kbhit() == 0:
    time.sleep(0.1)
  print('getting ch')
  c = msvcrt.getch()
  print(f'input: {c}')
  if c==b'e':
    exit()

When running in debug mode, msvcrt.kbhit() always returns zero and msvcrt.getch() never returns. Could it be fixed? Thank you.
