What is the difference? This is what was confusing me before.
As a convenience, the Python interactive interpreter prints the output
of any line you give it. So a line like this:
x = 1+2
doesn't print anything, because the result is stored as x. But a line
like this:
1+2
prints 3. This is *purely* a convenience feature, and it is only
activated in the *interactive* interpreter. When running as a script,
you need to explicitly call print to have things printed.
IDLE emulates that behaviour.
