使用 python tkinter 創建鍵盤快捷鍵並出現錯誤 TypeError: savF() takes 0 positional arguments but 1 was given

Question

我有一個名為 Mwin 的 tkinter Mwin我嘗試使用命令創建快捷方式Mwin是我的主 window 的名稱，其中包含我編碼的所有其他 tkinter 對象

Mwin.bind('<Control-s>', saveF)打開下面的saveF function

def saveF():
    files = [('CSV Files', '*.csv')]
    sFile = asksaveasfile(filetypes = files, mode='w', defaultextension=".dat")
    for i in range(10):
        sFile.write(date[i].get() + "," + timein[i].get() + "," + timeout[i].get() + "," + dHours2in[i].get() + "," + dHours2out[i].get() + '\n')
    sFile.write(dutyTimeinEntry.get() + "," + dutyTimeoutEntry.get())
    sFile.close

我的應用程序可以正常打開，但是當我按下 control 時，我收到消息：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.9_3.9.3568.0_x64__qbz5n2kfra8p0\lib\tkinter\__init__.py", line 1892, in __call__
    return self.func(*args)
TypeError: savF() takes 0 positional arguments but 1 was given

Answer 1

這有幫助嗎？

片段代碼：

def saveF(event):
    repr(event.char)
    files = [('CSV Files', '*.csv')]
    sFile = asksaveasfile(filetypes = files, mode='w', defaultextension=".dat")
    for i in range(10):
        sFile.write(date[i].get() + "," + timein[i].get() + "," + timeout[i].get() + "," + dHours2in[i].get() + "," + dHours2out[i].get() + '\n')
    sFile.write(dutyTimeinEntry.get() + "," + dutyTimeoutEntry.get())
    sFile.close

Mwin.bind("<Key>", saveF)
