Then we're back to square one:

Thank you for your response. I’m just starting out with Python and the
tutorials I have done are on 2.7.9. I will looking on to python3. It is
preloaded on Mac :-).

I find your argument convincing, that attempting to construct a Unicode
string of a lone surrogate should be an error.
Shouldn't the error type be a ValueError, though? The statement is not,
to my mind, erroneous syntax.

Hi all, I apologize for taking so long to reply, but neither my work schedule
nor the weather have been kind in the past week. That said, I've been thinking
long and hard about what everyone has said, and have decided that it would be
useful to write a wrap-up email that attempts to encapsulate

Hi Jason,
Thanks for the response. Okay, Will try to convert 'struct test' into
new python object (say 'PyStructTest') and include it inside
CountDictType as pyobject instead of 'struct'.
Will post details here, If i encounter any issues.
