item = random.choice(listValue) print("random item from list is:", item) 输出: random item from list is: 10 范例2: random.choices() 函数主要用于返回具有各种可能性的随机元素。该函数还对随机选择的数量进行加权(k)。例如,我们想从 5 个电影的列表中打印 3 个随机电影名称。 importrandom movieL...
Use therandom.choice()method: Thechoice()function takes one argument: the no-empty sequence like a list, tuple, string, or any iterable like range.Pass your list as an argument, and It will return a random element from it. Note: Thechoice()function returns a random element from the non...
So if we say "list of range 5," we’ll see that the range object consists of five numbers, from 0 to 4. 范围的输入参数是停止值。 The input argument to range is the stopping value. 记住,Python在到达停止值之前停止。 And remember, Python stops before it hits the stopping value. 这就...
6. shuffle(x, random=None) method of random.Random instance Shuffle list x in place, and return None. # 给列表随机排序,俗称“洗牌”函数>>> random.shuffle([1,2,3,4,5,6])>>> a = [1,2,3,4,5,6]>>> random.shuffle(a)>>> a[4, 6, 5, 2, 3, 1]>>> random.shuffle(a)>...
random 库是使用随机数的 Python 标准库,使用时候只需要 import random 即可。 从概率论角度来说,随机数是随机产生的数据(比如抛硬币),但是计算机是不可能产生随机值的,真正的随机数也只是在特定条件下产生的确定值,只不过这些条件我们没有理解,或者超出了我们的理解范围。
("'s", "volume and", "value leadership"), ("significant", "end-user", "experience"), ("transition", "from ", "to 's platform"), ("integrating", "shared", "services"), ("empowered to", "improve and expand", "our portfolio of experience"), ...
value = choice(seq) seq 可以是一个非空序列,如列表(list)、元组(tuple)、字符串(str),但不能是集合(set)。choice 函数会从非空序列中随机选取一个数据作为返回值。 2、实例 from random import choiceprint(choice(('you','me','them'))) #此时 seq 为元组(tuple)print(choice(['我','是','好'...
random.sample(Population, k),从指定范围内(Population)返回指定个数(k)的不重复的元素,注意,从Python3.9开始Population必须是有序类型,这就意味着set和dict将不能作为Population了,必须sorted排序之后或者转为list或者元组才能使用。官网:https://docs.python.org/zh-cn/3.9/library/random.html#module-random ...
We used Range(“E4”).Value to pick the selection number from Cell E4. CellsOut_Number = 7 is the first-row number to place the output. ReDim Array_for_Names(1 To xNumber) will resize the array for the selected names. CountA(Range(“A:A”)) – 3 determines names in the list....
2.3 Return value It returns a list of elements/elements randomly from a given population. 3. Usage of choices() Let’s take a list and pass it into the choices() function, to get the list of the single random element from the given list. If you do not specify the number of selection...
