如何为动态值生成pyarrow模式

import pyarrow as pa

def generate_pyarrow_schema(dynamic_value):
    # 确定动态值的数据类型
    data_type = type(dynamic_value)
    
    # 创建pyarrow模式
    schema = pa.Schema([])
    
    # 定义字段
    if data_type == int:
        field = pa.field("dynamic_value", pa.int64())
    elif data_type == float:
        field = pa.field("dynamic_value", pa.float64())
    elif data_type == str:
        field = pa.field("dynamic_value", pa.string())
    elif data_type == datetime.date:
        field = pa.field("dynamic_value", pa.date32())
    # 添加更多数据类型的判断和字段定义
    
    # 构建模式
    schema = schema.append(field)
    
    return schema

# 示例动态值
dynamic_value = 123

# 生成pyarrow模式
schema = generate_pyarrow_schema(dynamic_value)

# 打印模式
print(schema)
