It depends whether IDLE is opened with a subprocess or not. If it's a
subprocess, your program will have a separate interpreter entirely from
that used by IDLE, so the namespace will be the default namespace.
If IDLE doesn't have a subprocess, your program will be run in the same
interpreter as IDLE itself is running in, and since IDLE doesn't end
between runs of your program, all the variables you declare will hang
You could test this if you want. Do
then take out the import and run it again. If the print statement still
works, IDLE's not using a subprocess.
There have been many threads about this, it's usually a Windows issue.
