We will get a dictionary and by using the keys we can get the set values of the options of the Progress bar.
Here we can set the values of the options also.
my_dict=ttk.Progressbar(prg1)
print(my_dict['orient']) # print the value of orient
print(my_dict['mode']) # value of mode 

Number of tasks completed

While participating in any online survey you can see one progress bar reflecting the number of questions completed and number of questions balance.

Create one window with six pair of radio buttons where user has to select one choice for each question.

The progress bar will show the progress based on number of Choices made.
