需要帮助修复随机数

Question

我正在学习 Python 并且正在研究随机掷骰子。当我运行它时，它会重复在询问您是否要再次播放后首次显示的相同数字。我需要帮助找出我哪里出错了。

我试过移动代码并放置不同种类的代码。我只是被难住了。

import sys
import random
import time


greeting = "Welcome to my Dice Game!"
roll = "Lets roll this die!"
die = random.randint(0, 6)

print(greeting)
time.sleep(2)

answer = input("Want to play?")

while answer == "yes" or answer == "y":
    print(roll)
    time.sleep(2)
    print(die)
    answer = input("Want to play again?")
print("Thanks for playing!")

这是我得到的：

Welcome to my Dice Game!
Want to play?yes
Lets roll this die!
5
Want to play again?yes
Lets roll this die!
5
Want to play again?y
Lets roll this die!
5

Answer 1

您需要在循环中每次重新计算骰子的值，例如：

import sys
import random
import time


greeting = "Welcome to my Dice Game!"
roll = "Lets roll this die!"


print(greeting)
time.sleep(2)

answer = input("Want to play?")

while answer == "yes" or answer == "y":
    print(roll)
    time.sleep(2)
    die = random.randint(0, 6) # recompute it here instead
    print(die)
    answer = input("Want to play again?")
print("Thanks for playing!")

Answer 2

当您运行命令 die = random.randint(0, 6) 时，您告诉 Python 的是 "Use the random.randint() function to pick a random integer between 1 and 6, and then set the variable named die equal to the integer that got chosen"。完成后，您的其余代码不会执行任何操作来更新 die 的值。这意味着循环内的 print(die) 将继续打印它最初给出的任何值。换句话说，命令 die = random.randint(0, 6) 并不意味着 "Re-run the command random.randint(0, 6) and get another random number each and every time I refer to die"。相反，die 只是一些具有特定常量值的变量。

由于 random.randint() 是实际生成数字的原因，因此保持更新 die 的一种方法是简单地将循环外的命令移到循环内：

while answer == "yes" or answer == "y":
    print(roll)
    die = random.randint(0, 6) # Generate a new random number, then assign it to 'die'
    time.sleep(2)
    print(die)
    answer = input("Want to play again?")

事实上，如果你除了打印数字之外没有对数字做任何事情，你可以完全忘记使用变量，只需将 random.randint() 命令粘贴到 print 命令中:

while answer == "yes" or answer == "y":
    print(roll)
    time.sleep(2)
    print(random.randint(0, 6))
    answer = input("Want to play again?")
