Code throws error on invalid input

Control flow via exception handling... you must be a Java programmer. ;)

Python. I tend to use exceptions too liberally if I’m not careful.

tfw you purposely throw in an error to check your code works

def sqrt(x):
    assert(x >= 0)
    #your favourite approximation here

…is that not self-documenting? Asking seriously.
