你能在 python 中同时运行两个无限循环，一个有输入吗？

Question

我看过一些关于在 python 中运行无限循环的帖子，但没有涉及到这个特定主题。

我想知道您是否可以运行向用户询问输入问题的代码，而另一个无限循环在后台运行？ 抱歉，如果这很愚蠢，我是 python 的新手。

import time

num = 1
while True:
    num = num + 1
    time.sleep(0.1)

while True:
    ques = input("What is your favourite type of burger? ")
    if ques == "quit":
        break;

print(num)
# here i am wondering whether i can keep the first loop going while the second loop asks me questions

Answer 1

这可以使用线程来完成。

import time
from threading import Thread

num = 1


def numbers():
    global num
    while True:
        num = num + 1
        print(num)
        time.sleep(0.1)


def question():
    while True:
        ques = input("What is your favourite type of burger? ")
        if ques == "quit":
            break


threads = [
    Thread(target=numbers),
    Thread(target=question)
]

for thread in threads:
    thread.start()

for thread in threads:
    thread.join()

也就是说，这段代码没有做任何有意义的事情。
