Read python output from another python script

Question

I have two python files, one contains code which generates an output and the other needs to read it. The generation code is:

b=5
return b

The reading code is:

import os
c= os.system("test.py")
print (c)

When I run this, the output is 1. I don't understand why this isn't 5, any advise on how to fix this please?

Answer 1

Put all the code in your first file into a function.

#Fred.py
def frob():
    b=5
    return b

Then, you can import that function from any other Python file and see its return value.

#Barney.py
from Fred import frob
print frob()
#result: 5
