That depends on what you call 'long' or 'short'.
Halley's period is in the neighborhood of 75 years, give or take a few years.
Since that's short enough for two perihelions to occur within a single human lifetime,
I guess it ought to be considered a short period.
A comet with a period of 200 years or more.
Shoemaker-Levy 9 had a short period, as it was a comet that was first discovered in 1993 and eventually collided with Jupiter in 1994. The comet had been fragmented by Jupiter's gravity during a previous close approach, leading to its eventual collision with the planet.
Halley's Comet was a periodic comet; it returns to the inner system every 76 years. Hale-Bopp is a very long-period comet; it may have been last seen in 2215 BC. That may have been Hale-Bopp's first approach to the Sun; its orbit was likely altered by close brushes with Jupiter then, and again during its last pass in 1997. Hale-Bopp's next appearance may be in or around the year 4530 AD.
Halley's Comet has a nucleus (solid center) estimated to be about 9 miles (15 kilometers) wide. The most recently verified sighting of Halley's Comet was in 1986.

Not more than 200 years - less than 200 years. As to the "why", that's because this is how "short-period" vs. "long-period" is defined. Any comet that takes less than 200 years for one revolution is defined as short-period.

a long term comet is over 1 year a short term comet is from 0-3 months

A short-term comet is typically defined as a comet with an orbital period of less than 200 years, meaning it travels around the Sun and returns relatively quickly compared to long-period comets. These comets often originate from the Kuiper Belt, a region of the solar system beyond Neptune filled with icy bodies. Their orbits can be influenced by gravitational interactions with planets, causing them to become visible from Earth more frequently. Examples of short-term comets include Comet Halley and Comet Swift-Tuttle.
Hyakutake is a long-period comet. Before its most recent passage through the solar system, its orbital period was about 17,000 years, but the gravitational influence of the giant planets has increased this period to 102,070 years.
