Thank you!
Took a while to come to an approach like that.

hi,

pentadecatridecanylnonadecane is incorrect, but pentadecatridecylnonadecane could be, to the condition to had all the required positions. Now I get your question: no, you cannot have an in a ramification (except for the ...anoyloxy thing).
Do you still want this test to be added? ( -> C214H430)

Well, I'm asking 3 years old question

The tests seem to be OK. As written above, you might have a float vs. int issue, depending on the python version you used.

If you eat 2 cakes on the first move, your opponent can not eat 2 on the second move.

Thanks (and don't forget to upvote me :p): I think that with so much time spent doing test, it becomes kinda of a habit to prepare your code for edge test cases, no matter what.

I still have to figure out if that is a mostly positive thing or not ;)

I think your int-str conversion is useless.

What filter does is filtering out the items which do not satisfy the prerequisite(the lambda) in a.

The process is:
filter picks the items in a one by one and tests them by the lambda expression.
Each time, lambda accepts one item and returns a boolean value, filter will keeps down the item if lambda returns True or drops it while False.

The items returned from filter are picked from a directly(but not returned by lambda) and the lambda expression should always returns boolean value.
