Asking the user for your password with enter() is a bad plan because it’ll present up in plaintext since they’re typing it.

Copied! Unless of course usually instructed, print() will default to creating to straightforward output. Nonetheless, you can notify your running program to briefly swap out stdout for any file stream, in order that any output winds up in that file as opposed to the display screen:
