to test deprecated a module from importing

it's been challenging to do that simple task, which is put a print statement in the emptied module file. when it comes to testing, 
the first block is to how to test the output? one solution is to mock sys.stdout, the other is to wrap print in a function and patch it. 
the second block is the module is already loaded and won't be loaded again. Hence you need to reload it. for reload, py2 and py3 had a 
difference in where the reload comes from. here is the code to get around.

try:
    reload
except NameError:
    from imp import reload
