What causes “UserWarning: Discarded range with reserved name” - openpyxl

Question

I have a simple EXCEL-sheet with names of cities in column A and I want to extract them and put them in a list:

def getCityfromEXCEL():
    wb = load_workbook(fi         


        

Answer 1

In my case this warning shows up when filtering is on one of my worksheets. I wanted to suppress the warning so that it didn't bother my users and I just put this line in my code before the openpyxl.load_workbook call:

warnings.simplefilter("ignore")
