print((
    f"Information for {city.name}/{city.region}\n"
    f"Timezone: {city.timezone}\n"
    f"Latitude: {city.latitude:.02f}; Longitude: {city.longitude:.02f}\n"
))

print((
    f'Dawn:    {format(s["dawn"].strftime("%Y-%m-%d %H:%M:%S"))}\n'
    f'Sunrise: {format(s["sunrise"].strftime("%Y-%m-%d %H:%M:%S"))}\n'
