Section 4.6.1 says that the cmp and coerce functions are part of the core. These have apparently been removed or deprecated in Python 3.

Thanks for reporting this! Yes, quite right... and I missed removing those bits from 2nd edition as well.

I'll get the fix into the manuscript and hopefully it should make in before the final production process starts.

Thanks again for correction!
