我使用_thread模块(因为它更适合我的程序),我想将函数传递给我传入线程的函数。但是,有可能仅将元组转换为_thread.start_new_thread()函数,但函数不可迭代!Python 3:将函数传递给* args


@Willem Van Onsem - 这里是完整的代码。使用Pygame。

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.FULLSCREEN create a fullscreen display 
     pygame.DOUBLEBUF  recommended for HWSURFACE or OPENGL 
     pygame.HWSURFACE  hardware accelerated, only in FULLSCREEN 
     pygame.OPENGL  create an OpenGL-renderable display 
     pygame.RESIZABLE  display window should be sizeable 
     pygame.NOFRAME  display window will have no border or controls 
     """ 
     if depth != None: 
      screenx = self.screen = pygame.display.set_mode(dimensions, flags, depth) 
     elif depth == None: 
      screenx = self.screen = pygame.display.set_mode(dimensions, flags) 
     pygame.display.set_caption(caption) 
     return screenx 

    def __init__(self, dimensions, flags=0, caption='', depth=None): 
     self.winmode(dimensions, flags, caption, depth) 
     self.mainloopOn = True 


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

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

    def mainloop(self, func, subthread=False): 
     if subthread: 
      functuple = tuple(func) 
      _thread.start_new_thread(self.mainlooprunnerx, functuple) 
     elif not subthread: 
      self.mainlooprunner(func) 
    . . . 

if __name__ == '__main__': 
    root = PGMaster([1600, 900], pygame.DOUBLEBUF | pygame.RESIZABLE) 
    # vvv Real codes vvv 
    print(pygame.FULLSCREEN) 
    print(pygame.DOUBLEBUF) 
    print(pygame.HWSURFACE) 
    print(pygame.OPENGL) 
    print(pygame.RESIZABLE) 
    print(pygame.NOFRAME) 
    # ^^^ Real codes ^^^ 

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

输出:

Traceback (most recent call last): 
    File "C:\Users\User\Desktop\PyGameUI\__init__.py", line 127, in <module> 
    root.mainloop(myloop, True) 
    File "C:\Users\User\Desktop\PyGameUI\__init__.py", line 100, in mainloop 
    functuple = tuple(func) 
TypeError: 'function' object is not iterable

这不是真的我清楚你想达到什么样的,等你能给带有输入和一个错误消息/预期输出的例子吗? –

请勿使用以下划线开头的任何内容。这是python标记为“受保护”的方式,开发人员不保证其行为不会改变。 – gonczor

@gonczor它已被弃用,但我仍然使用它,因为我不想定义嵌套类 - 它会降低代码的可读性。从文档:“线程模块由于其弃用而在_thread中重命名”。 –

我已经想通了。 _thread实际上是不好。我已经重写了我的代码 - 现在我正在使用threading


我用tuple(func)代替tuple((func,))
