Python skipping functions when ran in VS Code

Question

I have written the following python code to read in XYZ data as CSV and then grid to a GTiff format.

When I run the code I am getting no errors.

However, after trying to debug, I added some print statements and noticed that the functions aren't actually being called.

How can I run this script so that it all completes?

Answer 1

Use

if __name__ == "__main__":
    app = gdal_toolbox(kwargs)
    app.run()

or

 if __name__ == "__main__":
    gdal_toolbox(kwargs).run()

Use thease codes at the end of your script.

Answer 2

It seems like you are not executing anything in this piece of code, just defining class and functions within it, right?
