Some Minor questions on Class and Functions

[joy99]

Dear Group,

I am trying to pose two small questions.

1) I am using Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.
1500 32 bit (Intel)] on win32 Type "copyright", "credits" or
"license()" for more information, on WINXP SP2.

As I am writing a code for class like the following:
IDLE 2.6.5
>>> class Message:
	def __init__(self,str1):
		self.text="MY NAME"
	def printmessage(self):
		print self.text

It works fine as can be seen in the result:
>>> x1=Message(1)
>>> x1.printmessage()
MY NAME

Now if I open a new window and write the same code value in
printmessage is giving arbitrary or no values.

Am I doing any problem in writing the code?

2) Suppose I have a code:

>>> def hello():
	print "HELLO SIR"

Can I write another function where I can call the value of this
function or manipulate it?

If any learned member can slightly help me out.

Thanks in advance,
Best Regards,
Subhabrata.
