yeah there are no mentions about triangle edges but decription has two examples that in my opinion is enough to understand what to do.

I don't understand what was fixed? The (random) test data?

Also, the description does not mention that the height and width of the triangle are always the same.

fixed, you will never get one point because the smallest triangle will have edge of one unit or three points

Area of triangle for edge=2
Log
['', '.']
0.0 should equal 0.5

Above list is from str.splitlines().

What is the area of a single dot triangle? Area of a point should be 0.0. Surely it's not 0.5!

This is the type of code that I love to maintain...
