>>> class my_class:
	def __init__ (self):
		self.name = ' my name is hi'
 
>>> a = my_class()  #Class instance
>>> print a
<__main__.my_class instance at 0x011E23F0>
>>> 
# This only show the class instance and memory location.
# So you see now that your code can not work.
 
>>> a.name  #call __init__(constructor)
' my name is hi'
 
>>> my_list= ['a','b']
>>> for x in my_list:
	print a.name, x	
 my name is hi a
 my name is hi b
 
This dosent make must sense.
 
Just one way that give a little more sense.
----------------
my_list= ['a','b']
 
class my_class:    
    def __init__ (self, name):
        self.name = name       
 
a = my_class('Tom')
 
for x in my_list:
    print 'Hi %s my name is %s' % (a.name, x)
 
output-->
Hi Tom my name is a
Hi Tom my name is b
