How to reload python module imported using `from module import *`

Question

I saw in this useful Q&A that one can use reload(whatever_module) or, in Python 3, imp.reload(whatever_module).

My question is, what if

Answer 1

When importing using from whatever_module import whatever, whatever is counted as part of the importing module, so to reload it - you should reload your module. But just reloading your module you will still get the old whatever - from the already-imported whatever_module, so you need to reload(whatever_module), and than reload your module:

# reload(whatever_module), if you imported it
reload(sys.modules['whatever_module'])
reload(sys.modules[__name__])

if you used from whatever_module import whatever you can also consider

whatever=reload(sys.modules['whatever_module']).whatever

or

whatever=reload(whatever_module).whatever
