how to run list of functions using Thread

Question

We have a file called functions.py and in that list f has 4 functions like :

f = [f1,f2,f3,f4]

which f[0]() call f1! the question is to call every list member using Thread and put the code in solve function ! but two notes are important :

1. Call all of members in on time!
2.  Threads could be not same as the others.

def solve(f):
    th=[]
    for i in range(4):
        x = threading.Thread(target=f)
        x.start()
        th.append(x)
    for anyt,j in enumerate(th):
        j.join()

What's the problem? could anyone helps me?

Answer 1

You could import the file with function onto the file where you're calling them in the solve function. 

import functions.py
def solve(f)
threads = list()
    for index in range(4):
        x = threading.Thread(target=thread_function, args=(index,))
        threads.append(x)
        x.start()
