如何增加 Python 多线程中的线程数？

Question

I am developing a multithreads app using Python3. I want to run over 100k threads at a time for backend server, but threads are created 10k in max. I think my server pc has enough resources for lots of threads.(cpu, ram). How can I increase the number of threads in Python3 multithreading?

for i in range(0, 1000000):
    t = i.Thread(target=func, args=(i))
    t_list.append(t)

for t in t_list:
    t.start()

I'm going to argue that "you shouldn't do that". It would be rare that you need that many threads, or that the system can handle it well. Threads are not a magic solution to deal with lots of incoming requests to process.

Instead, I suggest you create a limited number of threads in a "pool" and use a queue or similar mechanism to send tasks to the pool. See this answer for details on how to implement something like this.
