如何创建多值字典？

# 创建一个空的多值字典
multi_value_dict = {}

# 添加键值对，其中值使用列表存储多个值
multi_value_dict['key1'] = ['value1', 'value2', 'value3']
multi_value_dict['key2'] = ['value4', 'value5']
multi_value_dict['key3'] = ['value6']

# 添加键值对，其中值使用元组存储多个值
multi_value_dict['key4'] = ('value7', 'value8', 'value9')

# 添加键值对，其中值使用集合存储多个值
multi_value_dict['key5'] = {'value10', 'value11'}

# 访问字典中的值
print(multi_value_dict['key1'])  # 输出：['value1', 'value2', 'value3']
print(multi_value_dict['key2'])  # 输出：['value4', 'value5']
print(multi_value_dict['key4'])  # 输出：('value7', 'value8', 'value9')
print(multi_value_dict['key5'])  # 输出：{'value10', 'value11'}
