元组是不可变的序列,通常用于存储异构数据。 Tuples are immutable sequences typically used to store heterogeneous data. 查看元组的最佳方式是将其作为一个由多个不同部分组成的单个对象。 The best way to view tuples ...
You have seen that an element in a list can be any sort of object. 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:...
# You should not modify this cell, it contains imports and initial values needed to do work on either # the CPU or the GPU. import numpy as np from numba import cuda, vectorize # Our hidden layer will contain 1M neurons. # When you assess your work below, this value will be automatic...
tuple是有序异构容器,用于存储异构元素,列表一旦创建,其内容不可改变。 创建元组核查元素是否位于元组Append , Insert , Modify & delete 元组元素 创建元组 首先定义元组 代码语言:javascript 代码运行次数:0 运行 AI代码解释 1In [1]: # 直接创建元组,','分割,使用圆括号 2 ...: tupleObj = ('Riti', ...
3. The elements are guided by the serial number, and the specific element of the sequence is accessed through the subscript 序列类型：字符串、元组、列表 Sequence type: string, tuple, list 字符串：可以看成是单一字符的有序组合。字符串类型十分常用且单一字符串只表达一个含义，也被看作是基本数据...

通常,当我们使用数字时,偶尔也会使用其他类型的对象,我们希望使用某种类型的随机性。 Often when we’re using numbers, but also,occasionally, with other types of objects,we would like to do some type of r...
