Applying row height to all rows including and after row 7

[curranjohn46]

Using openpyxl, I cannot figure out how to apply a row height on an existing worksheet unless I do it one row at a time.

This works for a single row:

ws4.row_dimensions[14].height = 25

But I want to set the row height for row 7 and any subsequent rows.

This approach does nothing yet does not throw an error:

for rows in ws4.iter_rows(min_row=7, max_row=None):
    ws4.row_dimensions.height = 25
wb4.save('C:\\folder\\DataplusRows.xlsx')

Any idea how to do this? I can't glean the answer from the openpyxl documentation. And I can't seem to find examples anywhere.
