termios.error using pyinputplus.inputPassword in Mu

When running the script

using Mu-editor the input function errors with a termios.error: (25, 'Inappropriate ioctl for device')
When running from IDLE it inputs password in cleartext and hangs the shell with no error messages.

Start by reproducing the reported password-input script in Mu-editor and IDLE, focusing on the termios.error, cleartext input, and shell hang. Done means the behavior is understood and password input no longer errors, exposes cleartext, or hangs in the reported environments.
