Great Video Ryan - was reading a Pandas book, but your videos are more practical. Thank you for your time and efforts. Subscribed immediately and looking for more. Hopefully you can add a subquery using pandas some time in future.

why did we switch from transform to apply in lambda functions ?

[tomrhee]

I got a question for you. What if one of your data has missing values, sometimes every first day of the month or some column takes on a particular value every month? How would you handle the problem? I hope you can make a video for us.
