Call a function in another Python program

Question

I created 2 different "exe" with pyinstaller. I need pass arguments from program1 to program2 or run functions in program2 with program1's button click event, while programs are running. Is it possible?

Answer 1

Yes.

Keep both program1 and program2 in same folder,

#In program2.py
import program1  #or import specific function alone with "from program1 import myBtnClick"
program1.myBtnClick() 

Or to be specific,

from program1 import myBtnClick
myBtnClick()
