Python 如何将种子值全局设置为特定的数字？或许这是对的？

您好，只是一个简单的问题：如何在python中设置种子值并保持这种状态？这是正确的方法吗？在我的课程开始时，只做seed（20190101）。这是否也为我的所有职能奠定了基础？我只能找到随机种子模块的答案，而不是具体的答案

调用

random.seed

将更改从该点向前产生的随机数序列，无论这些随机数在程序中的何处产生。或者在什么地方使用它们，比如

random.choice

这能回答你的问题吗@这取决于你所说的“正确”是什么意思。大多数人在每次运行程序时都会尝试用不同的号码来调用它，所以每次都不会得到相同的“随机”号码。您决定在任何其他代码出现之前在文件顶部调用它。

import statistics as stat
from statistics import mean
from random import seed, choice
from math import hypot
import random
from turtle import *
import statistics
from statistics import stdev

seed(20190101)

def random_walk(n):
    x = 0
    y = 0
    for i in range(n):
        step = random.choice(["N","S","E","W"])
        if step == 'N':
            y = y + 1
        elif step == "S":
            y = y - 1
        elif step == "E":
            x = x + 1
        else:
            x = x - 1
    return (x,y)


all_steps = []
for i in range(50):
    walk = random_walk(100)
    all_steps.append(abs(walk[0]) + abs(walk[1]))
steps_mean = statistics.mean(all_steps) #Only after the loop
steps_max = max(all_steps)
steps_min = min(all_steps)
steps_variance = statistics.stdev(all_steps)
print("Max is",steps_max)
print("Mean is",steps_mean) 
print("Min is",steps_min)
print("variance is",steps_variance)
print("Pa random walk of 100 steps")




for i in range(50):
    walk = random_walk(1000)
    all_steps.append(abs(walk[0]) + abs(walk[1]))
steps_mean = statistics.mean(all_steps) #Only after the loop
steps_max = max(all_steps)
steps_min = min(all_steps)
steps_variance = statistics.stdev(all_steps)
print("Max is",steps_max)
print("Mean is",steps_mean)
