Python Set 并集运算详解：轻松掌握合并集合的高效技巧

A = {1, 2, 3}
B = {3, 4, 5}

C = A.union(B)
print(C)  # 输出 {1, 2, 3, 4, 5}

C = A | B
print(C)  # 输出 {1, 2, 3, 4, 5}

A = {1, 2, 3}
B = {3, 4, 5}
C = A.union(B).union({6, 7, 8})
print(C)  # 输出 {1, 2, 3, 4, 5, 6, 7, 8}

# 或者使用 | 运算符
D = A | B | {6, 7, 8}
print(D)  # 输出 {1, 2, 3, 4, 5, 6, 7, 8}
