Re: Python recompile

after the .pyc file was produced, or during? I suspect during.

No, the top-level code in the module is executed when the import is executed, not when it is compiled.  If the imported module hasn't already been compiled to bytecode, that needs to be done before the import can be completed.
In your example, "hello" will be printed when the module is imported, without any functions etc. within the module being called, but it's done when the bytecode is executed, not when it's compiled compilation.  If you ran the same program again (after the bytecode had been cached in a .pyc file) without modifying the source (so it doesn't need to be recompiled), you'd still get that output printed, even though the imported module isn't compiled again.
