Accessing a function variable from another file in python

Question

I have two files File1 and File2 . In File1 I have a function detect() defined as:

def detect():
    s = // some operations

I need to access this variable s in File2 .

I have tried declaring the variable as global but it has not worked.

How can I access the variable without creating a class as in this post or by using __main__ as in this post ??

Answer 1

function detect must be run to init its local variables.

def detect():
    detect.tmp = 1

def b():
    print(detect.tmp)

detect()
b()

of course you can import one python file as python module and call its functions like

from File1 import detect
print(detect.tmp)
