python关于type（）与⽣成器generator的⽤法 如果按这种形式写 type(a)(b)那此处的b是个可迭代对象，这个对象迭代完成后，再放到type⾥ from pymysql._compat import range_type, text_type, PY2 def _ensure_bytes(x, encoding=None):if isinstance(x, text_type):x = x.encode() #将str转化...
python中常规的写法是这样的,在一个for循环中,每次处理一行数据: 1defnon_generator_func():2'''3分析web server的log文件来判断所有传输的字节数4Non-Generator的写法:用一个for循环5:return:6'''7wwwlog = open("access-log")8total =0910forlineinwwwlog:11#获取字节数的字符串表示12bytestr = line.r...
for循环通过Python内置的next函数调用这个对象,直到对象抛出StopIteration异常为止。 试验一下: def randgen(total): for _ in range(0, total): yield random.randint(1, 100) g = randgen(88) print(type(g)) 执行上面这段代码,会打印出: <class 'generator'> Generator特征 Generator函数中没有return语句,...
