然后,get和set方法提供对每个变量的访问。这个类将在实践中使用如下: >>>c = Color("#ff0000","bright red")>>>c.get_name()'bright red'>>>c.set_name("red")>>>c.get_name()'red' 这不像 Python 青睐的直接访问版本那样易读: classColor:def__init__(self, rgb_value, name): self.rgb_v...

response对象是http.client.HTTPResponse类型,主要包含read、readinto、getheader、getheaders、fileno等方法,以及msg、version、status、reason、debuglevel、closed等属性。 常用方法: read():是读取整个网页内容,也可以指定读取的长度,如read(300)。获取到的是二进制的乱码,所以需要用到decode()命令将网页的信息进行解码...

In [212]: with open(path) as f: ...: lines = [x.rstrip() for x in f] 这样可以在退出代码块时,自动关闭文件。 如果输入f =open(path,'w'),就会有一个新文件被创建在examples/segismundo.txt,并覆盖掉该位置原来的任何数据。另外有一个x文件模式,它可以创建可写的文件,但是如果文件路径存在,...
