字节(Byte):计算机中数据的基本单位,通常包含8位(bit)。 整数(Integer):数学中的一个概念,表示没有小数部分的数。 字节序(Byte Order):字节在内存中的排列顺序,常见的有大端序(Big Endian)和小端序(Little Endian)。 Python中的字节处理 Python提供了多种处理字节的方法,其中bytes和bytearray是两种常用的字节序列...

bytearray(iterable_of_ints) Depending on the type of data we wish to convert into an array of bytes, the ByteArray class gives us 4 different constructors are shown in the table below. Examples of how to use each one are givenfurther down in the article. The table below shows the mos...

The optional source parameter can be used to initialize the array in a few different ways:If it is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode(). If it is an integer, the array will ...
