Python基础语法-基本数据类型-集合的运算

# 创建两个包含多个元素的集合
set1 = {1, 2, 3, 4, 5}
set2 = {4, 5, 6, 7, 8}

# 求两个集合的并集
set3 = set1.union(set2)
set4 = set1 | set2

print("set3:", set3) # 输出：set3: {1, 2, 3, 4, 5, 6, 7, 8}
print("set4:", set4) # 输出：set4: {1, 2, 3, 4, 5, 6, 7, 8}

# 创建两个包含多个元素的集合
set1 = {1, 2, 3, 4, 5}
set2 = {4, 5, 6, 7, 8}

# 求两个集合的交集
set5 = set1.intersection(set2)
set6 = set1 & set2

print("set5:", set5) # 输出：set5: {4, 5}
print("set6:", set6) # 输出：set6: {4, 5}

# 创建两个包含多个元素的集合
set1 = {1, 2, 3, 4, 5}
set2 = {4, 5, 6, 7, 8}

# 求两个集合的差集
set7 = set1.difference(set2)
set8 = set1 - set2

print("set7:", set7) # 输出：set7: {1, 2, 3}
print("set8:", set8) # 输出：set8: {1, 2, 3}

# 创建两个包含多个元素的集合
set1 = {1, 2, 3, 4, 5}
set2 = {4, 5, 6, 7, 8}

# 求两个集合的对称差集
set9 = set1.symmetric_difference(set2)
set10 = set1 ^ set2

print("set9:", set9) # 输出：set9: {1, 2, 3, 6, 7, 8}
print("set10:", set10) # 输出：set10: {1, 2, 3, 6, 7, 8}
