Python3:将函数传递到*args

Question

我使用的是_thread模块（因为它更适合我的程序），我想把一个函数传递给我要传递给线程的函数。但是，可以只将元组传递到_thread.start_new_thread()函数中，但是，函数是不可iterable的！你知道吗

@Willem Van Onsem-这是完整的代码。使用Pygame。你知道吗

class PGMaster:
    """
    Properties:
    mainloopOn - exits program if False

    Functions:
    PGMaster.mainlooprunner()
        Repeatedly runs Main function (must be overrided).
    PgMaster.mainloop(subthread=False)
        Wrapper for mainlooprunner. Subthread - will it run under MainThread? No if True.
    """

    def winmode(self, dimensions, flags=0, caption='', depth=None):

        Flags are:

        pygame.OPENGL        create an OpenGL-renderable display

    def mainlooprunner(self, function):
        func = function
        while self.mainloopOn:
            func()

    def mainlooprunnerx(self, *function):
        func = function[0]

    def myloop():
        print('Hello World!')
        return
    root.mainloop(myloop, True)

Output:

TypeError: 'function' object is not iterable

Answer 1

我知道了。_thread实际上是坏的。我已经重写了我的代码-现在我正在使用threading！你知道吗

我用tuple(func)而不是tuple((func,))
