How to limit the number of threads in Python?

Question

Python

Has a loop that currently creates a new thread for each element from the array:

for base in core_bases:
    name_thread = "thread %s " % (item_lst + 1)
    thread = CoreCheck(base, name_thread)
    thread.start()
    time.sleep(0.2)

How can we implement, let's say, a limit of 100 threads, clog 100 threads with a cycle, and if it is released, let's say 5th thread so that data processing occupies it, and so on.

Use a Pool
Instead of a process pool, you can use a thread pool:
from multiprocessing.pool import ThreadPool
