Question

I have results from a database search where some columns have dates, but not others. I need help to write

data = [['556644', 'Mr', 'So', 'And', 'So', Decimal('0.0000'), datetime.datetime(2012, 2, 25, 0, 0), '', False, datetime.datetime(2013, 6, 30, 0, 0)],...]

into an Excel spreadsheet so that

easyxf(num_format_str='DD/MM/YYYY')

is only applied to the datetime columns. I’m quite new to Python and I’ve been banging my head on this for quite a few days now. Thanks!

After simplifying your self-answer:

date_xf = easyxf(num_format_str='DD/MM/YYYY') # sets date format in Excel
data = [list(n) for n in cursor.fetchall()]
for row_index, row_contents in enumerate(data):
    for column_index, cell_value in enumerate(row_contents):
        if isinstance(cell_value, datetime.date):
            sheet1.write(row_index+1, column_index, cell_value, date_xf)
        else:
            sheet1.write(row_index+1, column_index, cell_value)
