Question

What is the best-practice method for verifying constructor params in Python?

I am new to the language, and am using raise:

class Breakfast(object):
    def __init__(self, spam=None, eggs=0):
        if not spam:
            raise Error("Error: no spam")

Is this stupid, or what?

Thanks!

If you are just trying to make sure that required parameters are passed, just leave off the default value. Python will then automatically throw a TypeError if a parameter is missing.

def __init__( self, spam, eggs=0 )
