Unit balancing

2006-09-13 Thread AbrahamLincolnIllinois 
Greetings!

I am working with a researcher who would be very happy if he could
include units in his calculations.  Then, if his complicated expression
didn't result in "kg/yr" the program would stop and point out his
error.

Does Python (or SciPy or ..) offer this feature?

Thanks for your help.

"Learning Python" 2nd ed. p479 error?

2006-05-26 Thread AbrahamLincolnIllinois 
Hello all.

On page 479, the 2nd edition of the "Learning Python" book, this code
appears

class Derived(Base):
def __init__(self, arg, *args, **kw):
self.__init__(self, *args, **kw)

Surely self.__init__ should be

Base.__init__

Everything else in the book has been crystal clear.  Up to page 479!
It doesn't appear in the errata.  What am I misunderstanding?

Thanks for your help, guys.  I'm convinced it is a bug, not a
misunderstanding.  I submitted it to the errata page at O'Reilly.
