Exceptions work rather similar to other languages, except that you can only catch them in IO code. So generally (IMO) it's better to reserve them for actually exceptional cases, and not throw them around like in Python. String interpolation can be done with external libs using quasiquotations. It's not very pretty this way, so typically string concatenation or printf is used. Of all the things, math-y is probably not the be best usecase for Haskell, when you can use Python, R, SageMath maybe, or Julia. Haskell is best for writing parsers, compilers, interpreters. Or if you need a rich static type system. If you throw in LiquidHaskell, you have pretty good tooling for writing mostly correct programs.
