Take care, this creates two *class* variables var1 and var2. For
*instance* variables, you want:

class Test:
  def __init__(self, var1='', var2=''):
    self.var1 = var1
    self.var2 = var2

> test1 = Test()
> test1.var1 = 'a'
> test1.var2 = 'b'

This creates instances variables var1 and var2 for test1 (shadowing
class variables).

p in 'onurb at xiludom.gro'.split('@')])"
