you are right, my bad. That is how i did, then (instead of copy/paste my snippet) I just started to change your code and ended up with this non-working snippet. There is also another error, because
i
is not defined at the moment. So working snippetfor row in range(10, 13): for col1, col2 in zip('BDFH', 'CEGI'): print(f'{col1}{row}:{col2}{row}')
