How do you write this in python

ok that makes some sense.

This cought my attention so I entered this into the shell to try to do
this very thing:

>>>class card:
      def setProperties(self, name, email):
         self.name = name
         self.email = email
      def show(self):
         print self.name + '/' + self.email

>>>ali = card('ali','ali at ali.com')

I got the following error:

Traceback (most recent call last):
  File "<pyshell#27>", line 1, in ?
    ali = card('ali','ali at ali.com')
TypeError: this constructor takes no arguments

I thought you said I could assign the properties at any place so I
defined them in the setProperties() method. What did I do wrong?
