# 連結
>>> a = [1, 2, 3]
>>> b = [4, 6, 6]
>>> a + b
[1, 2, 3, 4, 6, 6]

# 重複の削除
>>> a = [100, 20, 5, 10, 5, 20, 8]
>>> list(set(a))
[8, 20, 10, 100, 5]

# aの配列からbにある値を排除
>>> a = [1, 3, 5, 7, 9]
>>> b = [7, 3]
>>> list(set(a) - set(b))
[1, 5, 9]

# 両方の配列に含まれている値
>>> a = [1, 2, 3, 4, 5, 6]
>>> b = [2, 3, 5, 7, 11, 13]
>>> list(set(a) & set(b))
[2, 3, 5]
