Speaking as one such author, I think I do a reasonable job of this in
"Python in a Nutshell" (2nd ed): on p. 82 and 85 I have brief mentions
that "class attributes bound to functions are also known as methods of
the class" (p.82) and again that "functions (called methods in this
context) are important attributes for most class objects" (p.85); on
p.91-94, after explaining descriptors, instances, and the basics of
attribute reference, I can finally cover the subject thoroughly in
"Bound and Unbound Methods".  I realize that a beginner might be
confused into believing that "class attributes bound to functions" means
"function in a class", if they stop reading before p.91;-), but I don't
literally make that wrong assertion...;-)
