I doubt that is your actual code.  Python imports do not include .py 
extension.  Please show us your actual code.  (Use cut and paste 
please.)  And then take the time to tell us how you determine only the 
first is started.  Then we can probably help.

As an aside: To be sure, one could make the above imports work by having 
files named py.py and __init__.py in a directory named Worker1 (and the 
same for directories Worker2 and Worker3).   I think it's more likely 
that you miss-typed the above code.
