How to call a variable declared in a function in another python script

[lravikumarvsp]

Hi,

I had two python scripts r1.py and r2.py
In r1.py I used a variable named "test" in a function and I want to use this in r2.py.
I tried but not able to get it.
Please help

r1.py

test = 10
def f1():
	global test
	test = test + 100

r2.py

import r1
a = test + 100
print a

output: When I ran python r2.py

Output:
Traceback (most recent call last):
  File "r2.py", line 2, in <module>
    a = test + 100
NameError: name 'test' is not defined
