'big':表示字节序为大端序。 代码示例 下面是一个更详细的代码示例,演示如何使用float.to_bytes()方法: # 定义浮点数num=3.14159# 转换为字节序列,字节长度为4,字节序为大端序byte_array_big=num.to_bytes(4,'big')# 转换为字节序列,字节长度为4,字节序为小端序byte_array_little=num.to_bytes(4,'little...

byteorder:字节顺序,可以是 'big'(最高有效字节在前)或 'little'(最低有效字节在前)。 signed:是否为有符号整数,默认为 False(无符号)。 2. 识别to_bytes()方法调用中缺失的参数 根据你提供的错误信息,to_bytes() 方法在调用时缺少了必需的 byteorder 参数。这个参数是用来指定字节顺序的,对于整数到字节的...
