python-3.x - 带尖峰的随机数 gen

问题描述

我正在 python 中生成一些数据，如下所示：

import random
import time

def generate_random_data():
    pressure = float(random.randint(2409,2415) / 100)
    temp = float(random.randint(6989,7045) / 100)
    data = {"pressure": pressure, "temperature": temp}
    return data

if __name__ == '__main__':
    while True:
        rslt = generate_random_data()
        print(rslt)
        time.sleep(60)

但我还想做的是每隔一段时间在范围外产生一个尖峰......我怎么能在产生一个范围内的数字时做这样的事情？

解决方案

您的代码的一点更新：

import random
import time

def generate_random_data():
    peak_chance = random.randint(0, 100)
    is_peak = False

    if peak_chance < 10:  # 10% chance for under-value
        pressure = float(random.randint(2309, 2409) / 100)
        temp = float(random.randint(6889, 6989) / 100)
        is_peak = True
    elif peak_chance > 90:  # 10% chance for peak-value
        pressure = float(random.randint(2415, 2515) / 100)
        temp = float(random.randint(7045, 7145) / 100)
        is_peak = True
    else:
        pressure = float(random.randint(2409, 2415) / 100)
        temp = float(random.randint(6989, 7045) / 100)

    data = {"pressure": pressure, "temperature": temp, "peak": is_peak}
    return data


if __name__ == '__main__':
    while True:
        rslt = generate_random_data()
        print(rslt)
        time.sleep(1)

输出：
