    >>> soup = BeautifulSoup("Foo") 
    >>> soup.a.append("Bar") 
    
    >>> soup 
    FooBar 
    >>> soup.a.contents 
    [u'Foo', u'Bar'] 
    
    上面代码执行后,soup.a.contents 列表中有两项内容,但是下面代码执行后,列表中却只有一项内容,为何会有这个差别?感谢指点! 
    
    >>> soup = BeautifulSoup("FooBar")  
    >>> soup 
    FooBar 
    >>> soup.a.contents 
    ['FooBar']

    最后结果都是 list,第一个长度为 2,第二个长度为 1。这是列表的,不是 bs4 的。

    第一行应该写成==> soup=BeautifulSoup("Foo", 'lxml') 吧
