Question

我正在开发一个程序，根据获胜的百分比显示随机获胜者。这是一种可以帮助您更好地理解的算法：

询问多个用户的姓名。
程序应该询问他们是否需要更多玩家。
如果他们这样做，那么再添加3个玩家。如果没有，请继续。
完成后，计算0到100之间的随机整数。
向第一个玩家显示这个数字，以及他们必须赢得的百分比，然后是第二个，然后是第三个等等（他们的数字越接近100就越高）
选择随机获胜者，百分比较高的人应该更有可能获胜。
感谢用户玩游戏，并询问他们是想再玩还是退出。

如何根据随机数与100的接近程度确定合适的百分比？

我理解这些代码可能无关紧要，但我希望通过理解整个程序让我的问题尽可能地有意义 - 这可以帮助你更多。

到目前为止，这是我的代码：

#Luck Draw#
#=========#
import time
import random

print("You will be given a number, the closer your number to 100, the higher the chance you win!")

print("Player 1, please input your name.")
player1 = input()

print("Player 2, please input your name.")
player2 = input()
print("Player 3, please input your name.")
player3 = input()

morePlayers = input("Would you like more players?")
morePlayers = morePlayers.upper()

if morePlayers == 'YES':
    print("Player 4, please input your name.")
    player4 = input()
    print("Player 5, please input your name.")
    player5 = input()
    print("Player 6, please input your name.")
    player6 = input()
    print("** Unfortunately this program does not support more than six players yet! **")
    time.sleep(2.5)

    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player1num = random.randint(0,100)
    print(player1 + " Your number is:", str(player1num) + "! You have a percantage to win of: ")
    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player2num = random.randint(0,100)
    print(player2 + " Your number is:", str(player2num) + "! You have a percantage to win of: ")
    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player3num = random.randint(0,100)
    print(player3 + " Your number is:", str(player3num) + "! You have a percantage to win of: ")
    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player4num = random.randint(0,100)
    print(player4 + " Your number is:", str(player4num) + "! You have a percantage to win of: ")
    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player5num = random.randint(0,100)
    print(player5 + " Your number is:", str(player5num) + "! You have a percantage to win of: ")
    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player6num = random.randint(0,100)
    print(player6 + " Your number is:", str(player6num) + "! You have a percantage to win of: ")

    print("And the winner is...")
    time.sleep(1)
    print("...")
    time.sleep(1)
    print(winner + "!")
else:
    print("Calculating...")
    player1num = random.randint(0,100)
    print(player1 + " Your number is:", str(player1num) + "! You have a percantage to win of: ")
    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player2num = random.randint(0,100)
    print(player2 + " Your number is:", str(player2num) + "! You have a percantage to win of: ")
    time.sleep(0.75)
    print("Calculating...")
    time.sleep(3)
    player3num = random.randint(0,100)
    print(player3 + " Your number is:", str(player3num) + "! You have a percantage to win of: ")

Answer 1

I think what you are looking for is random sampling with probabilities assigned to each item. You will be wanting to make use of the numpy library.

Something like this might be useful for you.

import numpy as np
players = ["fred", "alice", "mary"]
probabilities = [0.2, 0.7, 0.1]     # probabilities of each player
winner = np.random.choice(players, p=probabilities)

Hope that helps.
