Hi Antonio,
Unfortunately, I don't think it's apparent whether or not a function
applies mutations or is a pure computation. In Python, those are by
convention or documentation rather than part of the language. There
are other programming languages can control the effects and scope of
mutation,

I can't claim to be new to programming, but I've dabbled in Python over and
over again to get small problems and puzzles resolved. One thing that I
find I can't keep straight are the methods that change a list in place, vs.
those that return a copy (sometimes transformed) of the list.

Hi Jordan,
You probably want to read up to chapter 3 (including the "Functions"
chapter) in "How to Think Like a Computer Scientist":
http://www.greenteapress.com/thinkpython/html/index.html
or some equivalent tutorial, so that you at least know what the terms
in the problem statement means.

Nope, any version of Python. If anyone is silly enough to be using
Python 0.9 (which is over 20 years old!) I can try to answer their
questions

I don't know why you would think importing sys would fix this.
docs say it accepts from sys.stdin
I now see that it is not necessary to import sys, although I am not sure
why.

I should probably clarify that this list is mainly for python2.7, correct

That is definitely more useful information in answering your questions.
Whenever you see the error you are getting:
NameError: name 'smv_guessNumber' is not defined
That means you are using a variable, in this case 'smv_guessNumber', that
has not been created yet.

Hint: "def" is the Python keyword used to define a function. You can
read all about def in the docs on python.org.
