因为这三种方法都和读取有关,因此open()函数中只允许写入的w模式和只允许追加的a模式不支持它们,而其他4种模式则都没有问题,举例如下: #w模式不支持read(),readline(),readlines() >>> file = open('test.txt','w') >>> print file.read() Traceback (most recent call last): File "<stdin>", ...

re.search(pattern, string, flags=0) 函数参数说明: 参数描述 pattern匹配的正则表达式 string要匹配的字符串。 flags标志位,用于控制正则表达式的匹配方式,如:是否区分大小写,多行匹配等等。参见:正则表达式修饰符 - 可选标志 匹配成功re.search方法返回一个匹配的对象,否则返回None。
