--text follows this line--

When I attempt to execute a command in a bash shell using python the python
command prompts for a password and that password prompt isn't hidden. In
what follows I'll replace my real password with the string FARGLE. Here's
the offending interaction in a bash shell buffer:

(cdp_validator) bash-4.4$ python3 -m twine upload  dist/*
Enter your usErname: toby.h.ferguson
Enter your password: FARGLE

As you can see, the password isn't hidden at all :-(

Executing the following elisp fixed the problem:

(setq comint-password-prompt-regexp
      (concat comint-password-prompt-regexp
              "\\|^Enter your password:.*"))

The general task here that the python is executing is pretty common:
uploading a package to PyPi.  So I would ask that you add that string as a
default to the comint-password-prompt-regexp
