如何从输入列表中随机选择一个项目？

Question

I am making a program that asks how many players are playing, and then asks to input the names of those players. Then, I want it to print a random player, but I can't figure it out how.

The code right now prints a random letter from the last name given, I think:

import random

player_numberCount = input("How many players are there: ")
player_number = int(player_numberCount)

for i in range(player_number):
    ask_player = input("name the players: ")

print(random.choice(ask_player))

Answer 1

You need to add each player name entered to a list. Here is a starting point of what you need in your code:

from random import choice

number_of_players = int(input("How many players are there: "))
players = []

for _ in range(number_of_players):
    players.append(input("name the players: "))

print(choice(players))

Answer 2

That loop reassigns the ask_player variable on each iteration, erasing the previous value.

Presumably you meant to save each value in a list:

players = []
for i in range(player_number):
    players.append(input("Player name: "))

print(random.choice(players))

Answer 3

The problem is that in each for-loop iteration, you are reassigning the ask_player var to a string. When you pass a string to random.choice(...), it picks a random letter of that string (since strings can be indexed like arrays). Just define an array before the loop and append on each iteration:

import random

player_numberCount = input("How many players are there: ")
player_number = int(player_numberCount)

players = []
for i in range(player_number):
    players.append(input(f"name player {i + 1}: "))

print(random.choice(players))

Answer 4

import random

player_number = int(input("How many players are there: "))
player_list = []


for _ in range(player_number):
    ask_player = input("name the players: ")
    player_list.append(ask_player)

print(player_list[random.randint(0, player_number)])
