[Tutor] Question on a example in the book "Learn to program usingpython" by Alan Gauld

[Klas Marteleur]

Sorry to bother you guys again with a few more "stupid" questions more, just 
so i understand everything correct.

 Is it correct...
1. that there is nothing in this program that "senses" which type of file i 
pass as a parameter?

2. that if you want to analyse a .txt file instead of a .html file, you change 
the last bit from "D = HTMLDocument(sys.argv[1])" to "D = 
TextDocument(sys.argv[1])"?

Kind regards
Klas
