Your problem is that you're trying to call an <code>async def</code> coroutine using the <code>threading</code> module. To make this work, you'll need to use <code>asyncio</code> to run an event loop in your <code>test</code> function. Assuming you don't care about the implications of a long-running call in your main thread, you can just directly use <code>run_until_complete</code>.

<pre><code>import asyncio

async def test2():
 server = client.get_server("345548250432012298")
 await client.change_nickname(server.me, "testing")
def test():
 loop = asyncio.get_event_loop() 
 loop.run_until_complete(test2())
 loop.close() 
def makeThing(nicks):
 frame = Tk()
 for i in range(0, len(nicks)):
 Button(frame, text=nicks[i], command= test).grid(row=i)
 frame.mainloop()
</code></pre>

If you need to make more async calls in one event loop, use <code>ensure_future</code> instead. Do note that you can break the async call off into its own thread using <code>threading</code> (as you correctly surmised) as long as you call the <code>run_until_complete</code> in the thread. 

This <a href="https://stackoverflow.com/a/26270790/4504895">answer</a> should help you use threads with asyncio (in that answer, <code>@asyncio.coroutine</code> is generally equivalent to <code>async def</code> <a href="https://stackoverflow.com/questions/40571786/asyncio-coroutine-vs-async-def">but there do exist some differences</a>) and this <a href="http://stackabuse.com/python-async-await-tutorial/" rel="nofollow noreferrer">async/await tutorial</a> should serve you well for general learning.

I am using Tkinter and discord.py together, and I want it to change the user's nickname on the press of a button. to change the nickname, discord.py uses the command <code>yield from client.change_nickname(server.me, string)</code>
but when I run that code in the command of a button, the function never get's ran. I have used a print statement to make sure, and none of the function gets ran. I have tried to use multi-threading to start the function, and that didn't work, any help would be appreciated

<pre><code>async def test2():
 server = client.get_server("345548250432012298")
 await client.change_nickname(server.me, "testing")
def test():
 threading.Thread(target=test2).start()
def makeThing(nicks):
 frame = Tk()
 for i in range(0, len(nicks)):
 Button(frame, text=nicks[i], command= test).grid(row=i)
 frame.mainloop()
</code></pre>

tkinter use yield from in button command

我同时使用Tkinter和discord.py，我想让它在按下一个按钮时改变用户的昵称。为了更改昵称，discord.py使用命令yield from client.change_nickname(server.me, string)，但当我在按钮的命令中运行该代码时，该函数从未运行过。我使用了一条print语句来确保...
