I am only in the beginning stages of learning Python.
I have a column, 'QUANTITY_SOLID', that I want to take the sum of all of its rows. I understand I can do this with 'SUMMARY_STATISTICS', but i'm not trying to create another entire table nor do anything other than simply SUM up that column. Once I have it summed up, I want to insert the sum into a new NULL field that I have created - I am attempting to do this via the 'CALCULATE_FIELD' tool.
Any helpful suggestions on where to go from here would be greatly appreciated, thank you!
