You can access tuple items by referring to the index number, inside square brackets:ExampleGet your own Python Server Print the second item in the tuple: thistuple = ("apple", "banana", "cherry") print(thistuple
my_tuple=(1,2,3,4,5) #访问第一个元素 print(my_tuple[0])#输出:1 #访问最后一个元素 print(my_tuple[-1])#输出:5 元组的特性 1、不可变性 元组是不可变的,这意味着一旦创建,元组的内容就不能被修改。例如,以下操作将引发错误: my_tuple=(1,2,3,4,5) #尝试修改元组的值 my_tuple[0]=10...

To access the items in a sublist, simply append an additional index:索引也是根据嵌套来的>>> x[1] ['bb', ['ccc', 'ddd'], 'ee', 'ff'] >>> x[1][0] 'bb' >>> x[1][1] ['ccc', 'ddd'] >>> x[1][2] 'ee' >>> x[1][3] 'ff' >>> x[3] ['hh', 'ii'] >>...
## can access the elements by index or slice ## include: string, tuple(or array? structure? cell?), list # basis operation of sequence type firstName = 'Zou' lastName = 'Xiaoyi' len(string) # the length name = firstName + lastName # concatenate 2 string ...
A Python® container is typically a sequence type (list or tuple) or a mapping type (dict). In Python, use square brackets [] or the operator.getitem function to access an element in the container. Scalar string arguments can be used to index into the container. ...
Tuple items are indexed, the first item has index[0], the second item has index[1]etc. Ordered When we say that tuples are ordered, it means that the items have a defined order, and that order will not change. Unchangeable Tuples are unchangeable, meaning that we cannot change, add ...
With one-dimension arrays, we can index a given element by its position, keeping in mind that indices start at 0. 使用一维数组,我们可以根据给定元素的位置对其进行索引,记住索引从0开始。 With two-dimensional arrays, the first index specifies the row of the array and the second index 对于二维数...
remove removes the first matching value, not a specific index, raises ValueError if the value is not found. pop removes the element at a specific index and returns it, raises IndexError if an invalid index is specified.Why the output is [2, 4]?The...
