-----------------------------+----------------------------------------------
At #8465, the following suggestions were made about the document
"Functional Programming for Mathematicians"
(sage/doc/en/thematic_tutorials/functional_programming.rst):
1. reduce will be part of the functools module in python 3. might be
helpful to import it from there to make it forward compatible
http://docs.python.org/library/functools.html <- or at least you might
wanna add a link to that module in the bottom section.
2. http://docs.python.org/library/itertools.html#itertools.starmap is
quite cool if you have "izip"ed values for the function arguments. i.e.
starmap(pow, [(2,5), (3,2), (10,3)]) --> 32 9 1000. it's like f(a,b) vs.
f(*c)
3. Besides that, have you explained the generator concept with the "yield"
keyword? I'm not sure if that counts as functional programming but it is a
nice topic in that context.
4. In the styles of programming section, the object-oriented example
seemed a little contrived, and I would say was bad style to make an object
for adding two things. I believe a better example would to use comparison
instead of adding. Something procedural
{{{
def compare(a, b)
return a - b;
}}}
versus like this for object-oriented
{{{
def class Comparable
def compare(b)
return self - b;
}}}
