运行时函数目标为multiprocessing.Process

Question

Is there a way to decide which function to run by the new process in run-time. (created by multiprocessing.Process )

Suppose I have 2 function

def f():
    print("In f")

def g():
    print("In g")

func_name = str(input("enter function to be run = "))

multiprocessing.Process(target = func_name, args = ()).start()

Now when I run the program

enter function to be run = f

This gives me error

TypeError: 'str' object is not callable

This seems obvious because the name of the function should match, but in this case the name is in the variable func_name as a string.

Answer 1

Use a dictionary:

functions = {'f': f, 'g': g}

multiprocess.Process(target=functions.get(func_name), args=()).start()

It would be better to make sure that func_name is actually in functions . You could also have a default function that could be given as a second argument to .get()
