how to access a variable from a .py script in another .py script

-2

I need to get the updated value of a variable(ex: results) , which is set in the main() function of a first.py script in the second.py script!

first.py

def main():
 results = os.path.abspath(r'D:results')
 return 0

second.py

-> need to access results here

Any help highly appreciated?

Something like this, but bear in mind you are returning 0, not result_path - from first import main; var = main(). If you need to access multiple variables inside the function, you could use a class instead and set them as attributes (from first import Main; cls = Main(); var = cls.result_path).

results is only known within the scope of main(), you cannot access it from anywhere else, not even from first.py.

You might want to start using pickle that allows you to save and load python objects to/from disk

You will need a function, which will then be imported, like:

from example.py import func()

Hope this helps.

In the file second.py

import first as f

main = f.main()
result = main.result_path

Please try this. I hope it helps a bit.

in this case adjust 'main()' to return result_path. I was more trying to access the variable in the second file and not to correct his first file. For me, as long he can access the file in the second path, the question should be answered. Please correct me if I am wrong.

You need to import your first script in your second and additionally set result_path as a global variable.

first.py:

result_path = None

def main():
 global result_path
 result_path = os.path.abspath(r'D:results')

second.py:

import first

access = first.result_path

You could also define a method in first.py, that just returns result_path and then call it in second.py, but therefor you'd still need to set result_path global.

Hi AracKnight Thanks ! this solution works . But currently i am facing another problem . Currently i changed my logic to update the 'result_path' variable dynamically based on the execution of first.py (not a hardcoded path i mean) , in that case I am unable to fetch it in second.py script now ! Stuck again i am calling first.py in second.py using subprocess.popen ()

Hi AracKnight Thanks ! this solution works . But currently i am facing another problem . Currently i changed my logic to update the 'result_path' variable dynamically based on the execution of first.py (not a hardcoded path i mean) , in that case I am unable to fetch it in second.py script now ! Stuck again i am calling first.py in second.py using subprocess.popen ()
