"GetPassWarning: Can not control echo on the terminal" when running from IDLE

Rather than deal with changing the current working directory in a terminal that has not started Python (which would mean you type something like python3 script.py--and it will fail unless the current working directory is already specified), start Python in your terminal and run this one-line command:

exec(open('C:\folder\script.py').read())

where you change the path string 'C:\folder\script.py' to match wherever your file is located on disk (the string does need to be specified with quotes).

Run your code in terminal, instead of the IDE. you will see that there is no more warning there. To run your code, enter this command in terminal:

python3 your_program.py

Use an actual terminal -- that is, an environment where stdin, stdout and stderr are connected to /dev/tty, or another PTY-compliant device.

The IDLE REPL does not meet this requirement.
