python - 查找有多少高于标准开发值

Question

现在，我想计算有多少天销售额高于平均值的 1 标准差。我该如何解决这样的问题？

average_value= input("What is the average value of sales a day?\n")
std_dev= input("What is the standard deviation of sales a day?\n")
days= input("How many days do you want to simulate?\n")

sales=[random.gauss(average_value,std_dev) for i in range(days)]

Answer 1

您不能获取 int 的 max 或 min，即 x。您需要列一个 list 。

import random

days = 10
average_value = 5.0
std_dev = 1.0

values = [random.gauss(average_value, std_dev) for i in range(days)]

>>> values
[4.610687715224258, 6.322701044169396, 4.584676199460875, 4.6351867518251595, 4.368399817684789, 4.201682562256684, 5.5211434405667354, 5.744873752293046, 4.885975367514446, 4.7502049666640405]

>>> min(values)
4.201682562256684

>>> max(values)
6.322701044169396
