我使用_thread模塊(因爲它更適合我的程序),我想將函數傳遞給我傳入線程的函數。但是,有可能僅將元組轉換爲_thread.start_new_thread()函數,但函數不可迭代!Python 3:將函數傳遞給* args


@Willem Van Onsem - 這裏是完整的代碼。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) 

輸出:

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

這不是真的我清楚你想達到什麼樣的,等你能給帶有輸入和一個錯誤消息/預期輸出的例子嗎? –

請勿使用以下劃線開頭的任何內容。這是python標記爲「受保護」的方式,開發人員不保證其行爲不會改變。 – gonczor

@gonczor它已被棄用,但我仍然使用它,因爲我不想定義嵌套類 - 它會降低代碼的可讀性。從文檔:「線程模塊由於其棄用而在_thread中重命名」。 –

我已經想通了。 _thread實際上是不好。我已經重寫了我的代碼 - 現在我正在使用threading


我用tuple(func)代替tuple((func,))
