Let's say I have a list of strings that will be the parameters of a function.
How do I start n threads (n being the length of the list of parameters), all executing the same function, each one with a parameter from the list?

that's too broad. And note that if you want to make processing faster, threads won't help as python uses GIL (global interpreter lock). You'll have to use multiprocessing instead. – Jean-François Fabre Mar 25 '17 at 20:24

Well but, how do I do this? – Mnovdef Mar 25 '17 at 20:32

import threading
single_params = ['param1', 'param2', 'param3']
threads = []
# f() will be a function that takes a single string parameter
for p in single_params:
threads.append(threading.Thread(target=f, args=(p))
for thread in threads:
thread.start()

True. I assumed you knew how to start threads. If not, this should be helpful https://docs.python.org/2/library/threading.html#threading.Thread – Charlie G Mar 25 '17 at 20:34

Could you be more clear? I mean, I know how to start threads one by one by hand, but can I automate the process, I don't know, with a for loop? – Mnovdef Mar 25 '17 at 20:37

I updated it but consensus seems that multiprocessing is the way to go – Charlie G Mar 25 '17 at 21:05
