I am trying to call the values of one function in the another function in the following way:
def func1():
num1=10
num2=20
print "The Second Number is:",num2
return
def func2():
num3=num1+num2
num4=num3+num1
print "New Number One is:",num3
print "New Number Two is:",num4
return
I am preferring not to use argument passing or using class? Is there any alternate way?

I think you've got the wrong group, but I don't know the best one for psychiatrists :) Seriously I can't see what you're trying to achieve with this approach. Can you explain it and I'm certain that we'll come up with a decent solution to your problem, whatever that may be.

A function's local variables only exist while that function is being
executed[1]. It's meaningless to try to access them from outside the
function.
[1] There is an exception (closures), but it doesn't have any bearing on
this particular problem.

You could make those variables global, see the "global" statement in the documentation of the language. However: I don't think that is a good idea and it will make your program more confusing to read than necessary, but go ahead and make that experience yourself. ;)
If you want, you can post your code here when done so that others might give you hints how to do things easier and cleaner, like e.g. putting spaces around operators and using four spaces indention (See PEP 8) or dropping the implied return from functions that return nothing. Apart from that, the above code is too short and with too little info what it's supposed to achieve, I can't really give you better advise.

Dear Group,
def func1():
num1=10
num2=20
print "The Second Number is:",num2
return
def func2():
func1()
num3=num1+num2
num4=num3+num1
print "New Number One is:",num3
print "New Number Two is:",num4
This works. Even you can incoportate some conditionals over func1() in func2() and run.
My question can I call its values of func1() too? What it is the big deal in experimenting we may come up with some new code or a new need?
Indentation slightly differs while you post, I agree. Return I just like too use.
Mark you are too concerned for me, thanks.

This does not work. Python does not get "compiled" in the same manner
as other languages (C, Java etc). Since you never call func2(), there is no
error. Once you try calling func2() you will see it does not work. func1()
does work.
The Second Number is: 20
Traceback (most recent call last):
File "subha.py", line 24, in <module>
func2()
File "subha.py", line 15, in func2
num3=num1+num2
NameError: global name 'num1' is not defined

It is not a big deal, that is how you learn. You are just writing code that
neither works nor really shows enough to tell us why or what you are trying to do. Not much I can do to guide or help you because I am completely lost
at your goal. The best I can do at the moment is say. func2 will not work.
You could return num1 and num2 from func1() and then it would work.
def func1():
num1=10
num2=20
print "The Second Number is:",num2
return num1, num2
def func2():
num1, num2 = func1()
num3=num1+num2
num4=num3+num1
print "New Number One is:",num3
print "New Number Two is:",num4
func2()

It's not 1964 any more and you're not programming in BASIC.
What you have just told us is that you prefer not to write good quality programs, and that you prefer to write buggy, hard to maintain code.
Of course that is your right to make such a foolish choice, but you shouldn't expect people to help you. There is enough terrible code in the world without encouraging people to write more.
If you would like to learn good coding techniques, please stay around here and pay attention to modern practices for writing good quality code. If you would rather stick to worst-practices from the 1960s, don't expect any encouragement.
Dear Group,
Absolutely brilliant, Ramit. Dennis also came with almost same answer. Using global may not give clean results everytime.
I wanted to say,
>>> def func1():
num1=10
num2=20
print "The Second Number is:",num2
>>> def func2():
func1()
num3=50
print "The New Number is:",num3
>>> func2()
The Second Number is: 20
The New Number is: 50
The post went slightly wrong sorry. No, I experiment myself on idle evenings to experiment with coding etc so I think of problems, practice on them and try to see if any better code evolves. Nothing else. I posted and Steve did not comment perhaps never happens. He rebukes me so much from my early days here, I just enjoy it.
