Is there a conflict of libraries here?

it was just to show that the symbol 'dt' refers to the module object for 
datetime, and the symbol 'datetime' refers to the datetime class from 
the datetime module - since they're different names they can coexist; 
earlier when you imported both as datetime, the second one overwrote the 
first one.  Sorry, I'm probably confusing you more.
