I am a complete beginner in Python... Currently I am trying to write a function which first checks whether the inputs x and y are int or float.

My guess which does the job is

`if (type(x) != int and type(x) != float) or (type(y) != int and type(y) != float):`

However, this seems quite clumsy / inefficient to me and will be difficult to generalise in case of many inputs. Therefore I think there should be a more elegant way to write this condition..? Thank you for any ideas!
