Python從類TypeError中的函式開始執行緒需要2個位置引數，但給出了3個

    def tfunc(this.args.dir, folder):
      for file in os.listdir(folder):
        this.executeFile(os.path.join(this.args.dir, file))

    def executeFiles(this):
      for folders1 in os.listdir(this.args.dir):
        for folders2 in os.listdir("downloaded/"   os.path.join(folders1)):
            t = threading.Thread(target=this.tfunc, args=(this, folders2))
            t.start()

就像標題所說的那樣，我在最后一次爭論后嘗試了逗號，但無濟于事。我究竟做錯了什么？請幫忙。

編輯：可重現的代碼。抱歉沒有直接發布。現在我無法添加代碼，因為它說代碼太多而文本不夠，所以我在這里盡可能多地寫，以便能夠發布代碼。

class MoodysParser :

def complete(this) :
    print(f"Complete")
    exit()

def executeFile(this, filename):
    print(filename)
    

def tfunc(dir, folder):
    for file in os.listdir(folder):
        this.executeFile(os.path.join(dir, file))

def executeFiles(this):
    for folders1 in os.listdir(this.args.dir):
        for folders2 in os.listdir("downloaded/"   os.path.join(folders1)):
            t = threading.Thread(target=this.tfunc, args=(this.args.dir, folders2))
            t.start()

uj5u.com熱心網友回復：

你不應該傳遞this給args. this將tfunc自動傳遞給。

t = threading.Thread(target=this.tfunc, args=(folders2, ))
