If you want all min/max pairs in the same row you can prebuild that row in a
list. With minimal changes to Cameron's code:
# untested
csvw = csv.writer(sys.stdout)
for city, coords in cities.items():
weather = ForecastIO.ForecastIO(
api_key, latitude=coords[0], longitude=coords[1]
)
daily = FIODaily.FIODaily(weather)
row = [city]
for day in range(2, 7):
day_data = daily.get_day(day)
row.append(day_data['temperatureMin'])
row.append(day_data['temperatureMax'])
csvw.writerow(row)
