QUESTION
I am trying to parse and save all the information between all the
tags in ('div', class_='WYSIWYG articlePage') into first column and all the information from the tag in ('div', class_='contentSectionDetails') into the second column in one .csv file (https://www.investing.com/news/stock-market-news/learjet-the-private-plane-synonymous-with-the-jetset-nears-end-of-runway-2419023). So the problem is that I have a thousands urls (URLs are generated based on numbers from the ALL_NUMBERS file) and I want to save this data in a single .csv file line by line from each url.
So I have the next code:

Well, I am new to BS in Python. I have written a code that scrapes HTML and save all the data that I need in csv file. The values from the ALL_NUMBERS file are substituted into the URL and thus a large number of URLs are obtained.
The code is below:

QUESTION
I'm having some confusion understanding immutable and mutable sets from Listing 3.5 in the Programming in Scala, 3rd edition book. The paragraph is telling me that it is creating immutable sets and, then updating it with +=, but then the new stored set contains all three elements. Some questions:
- How is this different from having a mutable set? Not sure I'm seeing the distinction.
- What happens to the old set that is existed before reassignment?
- Why bother calling it an immutable set if you can just reassign a new set to the
jetSet
variable? - Is someone trolling me and altered "mutable" and "immutable" in the PDF? (Don't worry, I've also bought the actual book which will arrive soon.)
The default way to create a set is shown in Listing 3.5:

is a var
. It references a new and different Set
after the +=
assignment.
What happens to the old set that is existed before reassignment?
If the previous 2-element Set
is not referenced by any other variable then it is garbage collected away.
movieSet
is a val
. It will always reference the same Set
even if that Set
mutates its value.
Mutation in general is considered undesirable and experienced Scala coders will avoid both of these scenarios.
