python规定括号中只有一个元素, 如(1)表示对该元素进行括号运算, 即单一元素元组是该元素本身, 如果要想表示一个元素的元组, 必须写成(1,) 在元素后面加一个逗号 >>> type((1,)) <class 'tuple'> 1. 2. 8. 序列 在python中,字符串(str)、列表(list)和元组(tuple)都是序列 操作函数 9. 集...
428 注意 Python不依赖于底层操作系统的文本文件概念; 所有的处理都是由Python本身完成的,因此是与平台无关的。429 buffering is an optional integer used to set the buffering policy. Pass 0 to switch buffering off (only allowed in binary mode), 1 to select line buffering (only usable in text mode...
