与str(python2)、bytes(python2/3)最大的不同在于,bytearray是个变长的玩意,当你用append之类改变它的内容时不会像bytes那种不可变对象那样新建一个实例,而更类似于list这种可变对象,对外引用不变,然而又不同于list,bytearray限制了元素的类型必为单个字节。顾名思义,bytearray是一个byte的array,用人话说就是字符数组。好处是可变,占用内...

分清function object、code object ,以及 bytecode >>> def double(a): return a*2 >>> double <function double at 0x000001D8082E48C8> 1. 2. 3. 4. 5. 为什么粘贴到这里对齐会是这样?先不管了。 从上面可以看到,定义一个函数之后,它就成了一个function object (函数对象)。只要不使用函数调用符号...
1)在Python 2中,print是一个语句(statement);在Python 3中变成了函数(function)。 2)无论py2,还是py3,与明文直接对应的就是unicode数据,打印unicode数据就会显示相应的明文(包括英文和中文) 3)在内存中的unicode,存到硬盘上或网络传输需要转成gbk/utf-8(自动转) ...
The default is to write files to their PEP 3147 locations and names, which allows byte-code files from multiple versions of Python to coexist. optimize specifies the optimization level for the compiler. It is passed to the built-in compile() function. Accepts also a sequence of optimization ...

Between Python 3.5, 3.6, 3.7 there have been major changes to theMAKE_FUNCTIONandCALL_FUNCTIONinstructions. Python 3.8 removesSETUP_LOOP,SETUP_EXCEPT,BREAK_LOOP, andCONTINUE_LOOP, instructions which may make control-flow detection harder, lacking the more sophisticated control-flow analysis that is ...
