Hello everyone,
As a Dynamo and Python beginner, I have a question.
I want to subtract every value in a list with every value in the same list, but not with itself.
For example, the list consists of:
15
12
18
implemented this means:
15-12
15-18
12-18.
However, the whole thing should be implemented in such a way that it also works with other list lengths.
Thanks for your help!
this is quite a good coding challenge, but I am missing some restrictions.
Should you filter by Unique answer or unique equations (which can still give the same answer )?
you can do:
15-12 (as suggested), but also 12-15 = -3, this is a unique equation.
should the awnser always be positive? if not, you have more combi’s?
Hmm, @superfabi.krause mentions that you should not apply the function on the same value
say:
15-15
Which happens if you use cross-product. Also, now the same equation happens more then ones?
after that we can simply remove the 0…it will be easy I think…but I don’t know an exact expectation of @superfabi.krause …
Thank you for your help! I think it works.
I’ll try that too! Thanks
