python如何循环一个函数等待而不暂停整个程序

Question

Many people here tell you to use threading but how do you have the rest of the program running while that thread sleeps, and reruns, and sleeps again.. etc. I have tried normal threading with things like a while loop but that didn't work for me

edit: so the question is: how do you sleep a thread without pausing the whole program in python, if possible could you give me a example of how to do it?

edit 2: and if possible without tkinter

edit 3: fixed it, it already worked but i didn't see it because printing doesn't work across threads... Silly me.

Answer 1

I think, you must look for asyncio library in python, which has capabilities for pausing and resuming your function and make your function as state machine. For your sleep requirement, there's asyncio.sleep function available. Refer to http://www.programcreek.com/python/example/81223/asyncio.sleep to see examples of asyncio.sleep.

Also refer to good article at https://hackernoon.com/asyncio-for-the-working-python-developer-5c468e6e2e8e#.frn3lo7vb

Answer 2

Silly me, threading works but printing doesn't work across threads. Thanks for all the help!
