I did some changes to default Python Template in Run/Debug and saved it by "Apply and OK". The change is to include PATH environment variable. I can see this template is used fo all my python file i run and it works. But once i close and restart the pycharm again all the changes i previously made to default Python Template in Run/Debug is no more there. I dont know why every time the pycharm is reverting the Run/debug python template back to its original default settings once it is restarted again. I am unable to find about this information in user manual. Please kindly help me how to permanently change the run/debug python template ? .
