I really enjoyed these examples. Thank you for sharing them. I have been looking for a way to fill a formula down a column, but have been unsuccessful in accomplishing this. The formula isn't as nice and neat as this is (wish it was that simple). It is =1/countif(M:M, M2), which I can easily do in excel, but haven't figured out how to fill this down the column using Python. My end row is 2776, so a few rows of data to deal with for a day. I am very new to Python, so my challenge is in applying the proper solution to the problem. Any suggestions or direction to another of your videos which may be relevant would be greatly appreciated.
