How do I compute derivative using Numpy?

Automatic Derivatives
Symbolic Differentiation
Compute derivatives by hand.

...T signal, this is how abort() basically works.
abort() is usually called by library functions which detect an internal error or some seriously broken constraint. For example malloc() will call abort() if its internal structures are damaged by a heap overflow.
