在 Python 中打印每个答案后如何循环

Question

我是否在此处添加“for”循环以及如何添加？ 我希望程序重复自己。

print('Ask a question')
import random

messages = ['It is certain',
    'It is decidedly so',
    'Yes definitely',
    'Reply hazy try again',
    'Ask again later',
    'Concentrate and ask again',
    'My reply is no',
    'Outlook not so good',
    'Very doubtful']

print(messages[random.randint(0, len(messages) - 1)])

对已发布代码的最小更改

import random
from random import randint

messages = ['It is certain',
    'It is decidedly so',
    'Yes definitely',
    'Reply hazy try again',
    'Ask again later',
    'Concentrate and ask again',
    'My reply is no',
    'Outlook not so good',
    'Very doubtful']

while True:
  question = input("What is your question? ")
  if question:
    print(messages[random.randint(0, len(messages) - 1)])
  else:
    break

更好但等效的while循环

while input("What is your question? "):
  print(messages[random.randint(0, len(messages) - 1)])

使用随机选择

随机选择

简化从列表中随机选择消息

while input("What is your question? "):
  print(random.choice(messages))

Answer 2

for i in messages:
        print(i)

这将遍历消息并打印变量消息

Answer 3

要为每次播放的消息打印随机消息，您可以这样编写，请参阅代码注释：

import random

messages = ['It is certain',
    'It is decidedly so',
    'Yes definitely',
    'Reply hazy try again',
    'Ask again later',
    'Concentrate and ask again',
    'My reply is no',
    'Outlook not so good',
    'Very doubtful']

user_input = ""
print ("Press enter to play or q + enter to quit")
# while user input doesn't equal q
while user_input != "q":
    # print a random message
    print(messages[random.randint(0, len(messages) - 1)])
    # ask for user input
    user_input = input()
