append() 添加单一元素在末尾 output: 添加一个list后,也是只添加一个list对象 output: extend() 迭代的添加每一个元素到list中,如果...
append('geeks') print my_list 输出: ['geeks', 'for', 'geeks'] 示例2:将列表添加到列表中 Python # my_list my_list = ['geeks', 'for', 'geeks'] # another list another_list = [6, 0, 4, 1] # append another_list to my_list my_list.append(another_list) print my_list 输出:...
another_empty_list = list()这两种方式都会创建一个没有任何元素的空列表。创建含有初始元素的列表 要创建一个包含初始元素的列表，只需将这些元素放在方括号中，用逗号分隔。元素可以是任意类型，包括数字、字符串或其他列表。例如：numbers = [1, 2, 3, 4, 5]strings = ["hello", "world"]mixed = [1,...
Python list.append list.extend 区别 一、 1. 列表可包含任何数据类型的元素,单个列表中的元素无须全为同一类型。 2. append() 方法向列表的尾部添加一个新的元素。 3. 列表是以类的形式实现的。“创建”列表实际上是将一个类实例化。因此,列表有多种方法可以操作。extend() 方法只接受一个列表作为参数,并...
3、扩展:将一个列表的元素全部加到另一个列表的末尾,即列表拼接。有点像append,但追加的是多个元素。语法:mylist.entend(another_list)。 示例: 4、排序:将列表中的元素按照顺序排列。语法:mylist.sort() 示例1: 示例2: 注:数字与字符串不能排列!
这里讲述的两个让列表扩容的函数append()和extend()。从上面的演示中,可以看到他们有相同的地方: 都是原地修改列表 既然是原地修改,就不返回值 原地修改没有返回值,就不能赋值给某个变量。 >>> one = ["good","good","study"]>>> another = one.extend(["day","day","up"])#对于没有提供返回值的...
029". I tried to remove it withstring.replace('\\xa0', ' '), but to no avail. It doesn't do a thing. I have a feeling that it has to do with the combination of numbers and characters, but that doesn't explain why it only happens when you try to append ...
>>> anotherList = [None, 'something'] >>> print aList [12, 'abc', 1.23, ['list', 'in']] >>> print anotherList [None, 'something'] >>> aList = [] >>> print aList [] >>> list('Python') ['P', 'y', 't', 'h', 'o', 'n'] ...

That includes another list. A list can contain sublists, which in turn can contain sublists themselves, and so on to arbitrary depth.Consider this (admittedly contrived) example:>>> x = ['a', ['bb', ['ccc', 'ddd'], 'ee', 'ff'], 'g', ['hh', 'ii'], 'j'] >>> x ['...
