Interactive wizard in wxpython (Phoenix) - wizard

Question

I am trying to develop an interactive wizard in wxPython 4.0(Phoenix) with Python 3.7. Basically the wizard has 4 pages(Stages). Each time I click Next, it should run a different Python script by taking the arguments on the page. I need to display the progress of the running of script on the wizard page.
I have already developed a basic interface for wizard with 4 pages. Now I need help on
1. How to pass arguments from the Page to the Python script?
2. How to call a different Python script everytime I click Next Button on the 4 Pages of wizard? (I think I need to write code around the event ON_PAGE_CHANGING, But I am not clear how to call a different Python script everytime I click NExt Button)
3. How to display progress bar of each script on the wizard?
I am attaching the code for my Basic wizard interface. I am new to WxPython, Any help on the above 3 points is greatly appreciated.
