Can you run two infinite loops, one with an input, at the same time in python?

Question

I’ve seen some posts about running infinite loops in python but nothing covering this specific topic.

I was wondering if you could run code that asked the user a question for an input, whilst another infinite loop was running in the background?
Sorry if this is stupid, I’m new to python.

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

This can be done using threads.

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()

That said this code doesn’t do anything meaningful.
