Thanks, powerpup118, I’ve actually found at the back of the book I mentioned earlier, that the author has included an appendix that has Python 3 to Python 2 code differences, which means I can still follow in the book, making slight changes to the code where needed, such as:
#Python 3 code:
my_name = input()
Compared to:
#Python 2 code:
my_name = raw_input()
There are only a small number of differences, mainly because this book is at such a basic level, so I should be good.
Had a look and found some interesting articles. Looks like the transition will be well-supported whenever it eventually happens.
Thanks again!
