Maybe. But stuff like The Perl Cookbook helped me a lot in the past.
[1] The chapter on iterators and generators is excellent, and full of useful ideas and code snippets you can reuse and build upon. I think a large part of that chapter was written by Raymond Hettinger, who also has designed and implemented much of those features in Python, IIRC. This book is written by many contributors, for the different sections and recipes.
[2] Interestingly, the Cookbook for Python 3 takes a somewhat different approach. It still has recipes, of course, but they are presented without too much discussion. The authors expect you to (and say so explicitly up front) use more of your time and thinking to figure out how they work (and to read the relevant Python and external library docs for the background information needed), rather than giving detailed explanations (not that the explanations in the previous edition are very detailed, but they are there). David Beazley and Brian Jones are the main authors of this one, IIRC.
Both models have their merits, IMO. In fact, overall, I think the approach of the Python 3 Cookbook may be better, at least for experienced programmers, because it makes you think and do more on your own (using the book as a base), from which you grow more as a programmer.
It’s why my Programmer’s Compendium [0] may only ever be useful to me. If you try looking at some of the more complete pages there, you might think they’re useless, but they’re, in fact, all that I need to write down.
However, mine is public, and there’s not much harm in these things being public, because perhaps it can be useful to someone else one day. I would encourage people to share knowledge by default.
So while I also think making it public is a good idea, I would also say never be under pressure to make it accessible to others!
What’s good for learning is almost never good for reference.
