The best Programming books?

[Larz60+]

This is a great book, and now free, Machine Learning by Ian Goodfellow, Yoshua Bengio and Aaron Courville: Now Online free by MIT: http://www.deeplearningbook.org/

Exercises here: https://github.com/goodfeli/dlbook_exercises
Lectures here: http://www.deeplearningbook.org/lecture_slides.html
Discussions: https://www.commonlounge.com/community/e...658ef85cb1
Videos (downloadable) for every chapter: https://www.youtube.com/channel/UCF9O8Vj...-Pg/videos

I wrote a quick down-loader for the videos, I did not include the book club videos, so if you want them, add to the dictionary.
Before using, change basepath if you would like the videos to download to another directory.
As written, they will be downloaded to 'videos', which if it doesn't exist will be created.

I have included two functions to save and load the dictionaries to and from a JSON file. You can create a separate script to create the dictionary, and replace with a call to 'load_url_list' once the JSON file exits.

This program requires pytube which can be downloaded (from command line) with:

pip install pytube

Here's the (quickly tested code)

        os.chdir(os.path.abspath(os.path.dirname(__file__)))

    def downloadYouTube(self, videourl, path):
        yt = YouTube(videourl)
        yt = yt.streams.filter(progressive=True, file_extension='mp4') \
            .order_by('resolution').desc().first()
        if not os.path.exists(path):
            os.makedirs(path)
        yt.download(path)


def save_url_list(basepath, url_list):
