Keep getting this in PyDev "TypeError: quiz() takes exactly 1argument (0 given)"

Hi all, I cannot figure why I keep getting this error. It is my understanding that all methods need a self argument when designing a class. Here is my code:

import random

print self.question
self.ans = raw_input('Answer: ')

if self.ans == self.elements(self.question):
self.numCorrect += 1
else:
self.insult = random.choice(self.reply)
print 'Incorrect %s' % self.insult



if __name__ == '__main__':

quiz()



Thanks for any help!

You need to instantiate your class:

foo = ElementsQuiz()
foo.quiz()

That doesn't work either for some reason. I keep getting "NameError: name 'ElementsQuiz' is not defined"

Thanks for the help guys! I finally got it working. Shouldn't I technically call quiz() through the constructor, though? Otherwise, the constructoris pointless. I just put in pass for now. (Also, I always thought that if __name__ == '__main__': went IN the class. Why wouldn't it be apart of the class? )

Thanks again!

What language did you use before trying Python? Was it java, by any
chance, where everything has to be in a class? If you're going to do
everything from the "constructor", then why on earth would you make it a
class?

(Incidentally, __init__() is the initializer, not the constructor, which
is called __new__() )

If you want to make a proper class out of it, you'd move the
initalization code into the __init__(), call, the stuff that only needs
to be called once per instance. On the other hand, you have a class
attribute 'elements, which gets initialized outside of any mmthod. And
everything else is just locals.

Seems like you're arguing both sides. Anyway, the if __name__ stuff
does not belong inside any class. This is Python.
