Start multiple threads given a list of parameters [duplicate]

Question

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

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()
