python – OPENPYXL, Finding the next row with no value so that I can add the next items

How do I create a function that gets the next row that has no value.
Image of Worksheet, I’m working on

This is what I had come up so far,

def get_row(file):
wb = load_workbook(file)
ws =
cells = ()
for row in ws.iter_rows(min_row = 2, max_col = 7, max_row = 5):
    for cell in row:
        if cell.value == '':
