David: The dynkin_diagram method does return a string. However, it has a
newline character in it, so you need a print statement to make things show
up in two lines, rather than one line with a \n.

Additionally, regarding PR 2344, in my docstring for dynkin_diagram.py I
have a print statement:

Pursuant to Upabjojr's comments
(https://github.com/sympy/sympy/pull/2237/files#r5289892), I've updated
some bits of my code to use the __new__ function instead of __init__. For
example in cartan_type.py, in class Standard_Cartan, I have a __new__
method which goes as

All the Travis tests passed on the latest build (except one that timed

a look at implementing what Upabjojr had to say about __new__ versus

Looks like the c in list(c) is a Python int, so if you do list(c),
it returns an error. What is this line supposed to do?
Does this happen when you run this doctest locally? That's the best
way to debug it.
Ondrej
Unfortunately, I don't seem to be able to run the doctest locally.
Okay, now that I've fixed the import, there is another Travis error about
the doctests that I do not understand. When running the doctests for
type_A, travis gives the following error:
Failed example:
c = CartanType('A4')

Ondrej,
When I run test_type_a.py on my computer, it is passing without the error
that you get. When I apply the patch:
def __call__(self, *args):
c = args[0]
+print c
c = list(c)
for me, it does just print out A3 or A4, it does not print out anything
else.
I am testing:
8afd72682a924195f94f76cd25e70ac00d28ac27
as well. When I run git diff the only difference is adding the print
statement to cartan_type.py.
