接下来,我们可以绘制一个状态图,展示在不同操作下bytearray的状态变化: Create bytearray()bytearray(data_bytes)print(bytearray)EmptyCreatedAssignedPrinted 结尾 通过以上步骤,你已经成功地将一个bytes对象赋值给了一个bytearray对象。这一过程涉及了对象的创建、转换以及结果的验证,帮助你更好地理解了 Python 中这...

So far we have constructed ByteArray object from already available data, to end this section let us see how to create an empty ByteArray object to which we can add stuff later on. Creating Placeholders If we wish to create an empty ByteArray class without any elements you can use the fol...
