I am creating a GUI which use external Python script function with parramters for calcualtion and updating progressbar.I had used multithreading.It works fine for first run but if I change dropdown and lineedit parameter and click again on calculate button it does not respose.
I have three level dropdown on basis of that we select python script for running function by using csv sheet for calcualtion. GUI image is attached [GUI image for calcuation][1]
This is My code
