How to use a variable's value from 1 method to another method?

Question

def sum():
a =2
b=5
s= a+b
return s

def add():
c=5
print(s+c)

add()

This show error: s not defined..

How can use 's' value in my add() method?(without using global)

Answer 1

I am a little confused about this code. May be this is a snippet of a more complete code?
For this situation now: if you just call add(), s is not existing at all, because it's only created if the function sum() is called. But if you call sum() like this:

s = sum()

*s* is available because sum returns the content of s.

So you can do:

def sum():
a =2
b=5
s= a+b
return s

def add():
c=5
print(s+c)

s = sum()
add()

# output : 12

Answer 2

Just write in the add function:
s = sum()

Answer 3

Use `global s`.

Answer 4

o.gak without using global..i forgot to write it in the description..

Answer 5

You must first call sum function. So "s" will be defined and then you can call add.

Answer 6

Amit Dubey As I know, `global` is used for this case.
But you say "without". This is out of my knowledge...
And what do you do this for? for what case?
Also, without sending a parameter?
