如果没有响应，则向用户提供提示

Question

我正在尝试创建一个程序，该程序要求用户输入一个问题的三个答案。现在我的问题几乎是一段长的，但理想情况下，我想先问一个初始问题，然后如果用户在任何时间内没有输入任何内容，就开始给出提示。

answers = []
def questions(question):
print(question)
for i in range(1, 4, 1):
answers.append(input(f"{i}. "))
questions("""What are your three favorite things? """)

理想情况下，会有一些行为类似下面的伪代码：

ask user for input
if no response within 30 seconds:
give first hint
elif no respose within 30 seconds:
give second hint        

提前感谢！

Answer 1

您可以创建一个hint进程，在其中等待一段时间，然后输出提示。如果用户回答了问题，请使用terminate((终止hint进程。

import time
from multiprocessing import Process
answers = []
def questions(question):
print(question)
for i in range(1, 4, 1):
answers.append(answer(f"{i}. "))
print(answers)

def hint():
# For testing simplification, I decrease the wait time
time.sleep(5)
print('nhint1 after 5 seconds')
time.sleep(3)
print('hint2 after 3 seconds')

def answer(i):
phint = Process(target=hint)
phint.start()
uanswer = input(i)
phint.terminate()
return uanswer
questions("""What are your three favorite things? """)

输出看起来像

What are your three favorite things? 
1. 
hint1 after 5 seconds
hint2 after 3 seconds
test
2. 
hint1 after 5 seconds
test1
3. test3
['test', 'test1', 'test3']
