I saw some questions about it in stackoverflow (links below), and also find it very useful to have the ability to print asterisks.
Some users, find it disturbing when they don't have any indication that password is typed, and it will be helpful to have it.

I know that it's have some risks exposing the number of chars to the password, but I think it's worth it.

When using Jupyter (notebook server is 4.3.1) the password does echoed as "*", but not in Python IDE in linux and Windows
