貌似没有库可以直接地兼容，你得在了解了 DataOutputStream 的二进制格式之后，通过 Python 的 struct 库来读取。摘抄上述链接的部分代码如下：

DataOutputStream daos = new DataOutputStream(baos);
daos.writeLong(value1);
daos.writeInt(value2);
daos.writeBoolean(value3);

result = struct.unpack('>II', input1)
value1 = (result[0] << 32) + result[1]
result = struct.unpack('>i', input2)   // result[0] becomes value2
result = struct.unpack('>b', input3)   // result[0] is 1 for true and 0 for false
