Question

I’m trying to do something like this:

import threading
def func1(a,b):
    def func2():
        t=threading.Thread(target=func3)
        return t
    return func2

func2=func1(a,b)
func2()

I have a restriction(the language I’m using is python with some restricted functions) not to use the args parameter for the Thread function instead I want to pass a and b as parameters to func3. How can I do this using closures?

Answer 1

In the absence of lambda I might look into functools.partial. If that isn’t allowed, you could probably do:

import threading
def func1(a,b):
    def func2():
        def func4():
            return func3(a,b)
        return threading.Thread(target=func4)
    return func2

func2=func1(a,b)
func2()
