Yeah, the aim isn't to grill them on the minutia, but to get a
feeling that they know the basics.  The zipfile module offers a
ZipFile object for reading/writing zip files with or without
compression.  The CSV file allows for reading/writing CSV files with
definable delimiters and quoting/escaping.  Etc.

The ability to know off the top of your head that it's the "Python
Debugger" is more than enough :-)  That's just first-order
ignorance:  you know what you don't know and can spend a few minutes
reading up on it if you need it.  The second[or higher]-order
ignorance of not knowing what pdb is (or, if you need more powerful
debugging, how to do it) is sign the person hasn't been programming
in Python much.

I'd even be satisfied if a person just knew that such features
weren't there all along and might need to be worked around for older
deployments.

[Ed: something appears to have gotten truncated there]  Yeah, it's
more about a person being sufficiently steeped in python to know
bits and pieces of the zen, and their ability to recognize/create
pythonic code.  I've seen enough Java-written-in-Python to know what
I don't want :-)
