and, in particular, explicit vs. implicit type casts of those objects.

Examples:

Python: strong, dynamic

PHP: weak, dynamic

C: weak, static

Haskell: strong, static

I expect that everybody doing this job has a CS or equivalent degree and knows the difference between strong / weak and static / dynamic typing. Reading other comments here demonstrates this is not the case. This is not a bad thing (luckily we only need a screen and a keyboard) but hopefully they'll have learned something new today.

Btw, there is a lot I don't know despite my degree. No hard feelings.

      if a>b:
         return a/b
      else:
         return None
