Code below uses regex to replace blanks with NaN. And pandas count for non-NA cells. # Import library import pandas as pd # Create DataFrame newDF = pd.DataFrame({ 'Paid_Off_In_Days':[1, np.nan, 15, ' ', 18, 29] }) # Regex to replace blanks with NaN newDF = newDF.replace(r'^\s*$', np.nan, regex=True) # Get counts counts = newDF.count()

In this tutorial, we will learn how to write an Excel formula in Python that counts the number of non-empty cells in a column. We will use the COUNTA function, which is a built-in function in Excel. The COUNTA function counts the number of cells in a range that are not empty.
COUNTA will give the number of cells in a range that are not empty. So try ... =IF(NOT(COUNTA(BM2:BQ2)),"","Major Milestone Due")
