Overall, this is a lecture that gives you the confidence that you can do it once you've learned everything. For your information, in the case of the last part regarding cufflinks, there hasn't been an update for about 6 to 8 years, so there will be compatibility issues between NumPy/Python and the versions used by current or future students. If that's the case, you should run it by setting Python to around version 3.10 from the start. Otherwise, you might need to create a separate virtual environment and downgrade Python and NumPy there. If you don't want to deal with that, I think it's fine to skip the cufflinks section. The overall quality of the lecture is solid, and it's well worth the money. I would highly recommend it to many people :)
