Not all of it -- only a tiny region near the South Pole experiences 6 months of continuous daylight followed by nearly 6 months of continuous night. The North Pole has a similar division between day and night, each lasting one half of the year.
However, practically all of Antarctica experiences at least 24 hours of continuous day or night, and weeks or months of continuous day or night occur in various locations.
*Because of the width of the solar disc, and refraction by the atmosphere, there are about 2 or 3 more days of daylight per year than there are of night.
Alaska
Sweden is the country having six months day and six months night because it is located in the north pole. However I think that Antarctica is also having long days and long nights because it is in south pole.
The sun is above the horizon for 6 months and below the horizon for 6 months, only at the earth's north and south poles. Those points aren't part of any countries.
No location, even in northernmost Alaska, has 6 months of day or night. Only the North Pole or the South Pole will have 6 continuous months of daylight and 6 continuous months of night, because they are alternately tipped toward or away from the Sun. Only one half of a planet (sphere) can be illuminated at any one time. A pole, the end of a planetary axis, is either tilted toward the sun, and stays in the Sun as the Earth spins, or tilted away from the Sun, and cannot move into daylight. Areas within the Arctic Circle or Antarctic Circle (a latitude of 66.6 degrees or more) will experience one or more days of 24 hours of sunlight, and conversely one or more days of 24 hours without sunlight. The closer one gets to a pole, the longer or shorter this period of continual day or night, which is popularly described as the "midnight sun" and the "polar night." The effect of twilight reduces the actual periods of nighttime darkness, but the Sun will also never rise very high in the sky even in summer. Locations that experience the phenomenon are northern parts of Alaska (US), Canada, Greenland (Denmark), Iceland, Finland, Norway, Sweden, and Russia. In Svalbard, Norway, the sun does not set in summer, but circles the horizon from April 19 to August 23. Large uninhabited areas of Antarctica also experience extended days and nights, but only near the South Pole are they about 6 months long.
Only at or close to the South Pole will there be 6 months of daylight, and nearly 6 months of night. The Earth is tilted on its axis with respect to the plane of its orbit. The ends of that axis, the poles, must be either tipped toward the Sun, or tipped away from the Sun. As the Earth spins, the pole facing the Sun is always in sunlight, and the pole facing away has none. Only 1/2 of a planet can be illuminated at a time, and except on one day twice a year, the North Pole and South Pole are never both in daylight. At the equinoxes, the Sun may be visible from both poles. When Antarctica is tipped toward the Sun (approximately September 21 to March 20, summer in the Southern Hemisphere), the Sun is up continuously, circling the horizon. Beginning on March 21, the sun does not rise above the horizon until the following September.
Well, in Antarctica there's 6 months of day followed by 6 months of night. Does that count?
Yes and no. Antarctica has 6 months of day and 6 months of night. It doesn't all happen every 12 hours. But in other countries yes.
Sunrise at the South Pole is on about the 21st of September every year. Sunset is on about the 22nd of March the following year. The reverse is the case at the North Pole. So a polar day is about 6 months and a polar night is also about 6 months.

Yes, Antarctica stays dark for about 6 months all day long, then after that there is daylight for 6 months because of its angle toward the sun.
Only at the Earth's north and south poles.
In Alaska there is 6 months day & night
Sunrise at the South Pole is on about the 21st of September every year. Sunset is on about the 22nd of March the following year. The reverse is the case at the North Pole. So a polar day is about 6 months and a polar night is also about 6 months.
