Updating Data from Kivy Python to Excel

Question

I have a problem on updating data that I want to insert to excel. At first, I create the data and it work successfully without error. After I want to insert new data from Kivy, it doesn't work. Error said that the process denied by PC. I had watch tutorial and it seem my problem still unsolved. Here is my code from VSCode:

Window.size = (500, 500)

outWorkbook = xlsxwriter.Workbook("staff.xlsx") outSheet = outWorkbook.add_worksheet()

class Menu(Screen): pass

class Enter(Screen):

input1 = ObjectProperty(None)
input2 = ObjectProperty(None)
input3 = ObjectProperty(None)
input4 = ObjectProperty(None)
input5 = ObjectProperty(None)
input6 = ObjectProperty(None)

def clear(self):
    self.ids.inherent_input.text = ''
    self.ids.inherent2_input.text = ''
    self.ids.inherent3_input.text = ''
    self.ids.inherent4_input.text = ''
    self.ids.inherent5_input.text = ''
    self.ids.inherent6_input.text = ''

def btn(self):
    self.L = ()
    print("Name: " + self.input1.text,
        "Activity/Programme: " + self.input2.text,
        "Date: " + self.input3.text,
        "Place: " + self.input4.text,
        "Time from: " + self.input5.text,
        "Time to: " + self.input6.text)

    
    staff = ({"Name": [str(self.input1.text)], "Program/Activity": [str(self.input2.text)], "Place" : [str(self.input3.text)], "Date": [str(self.input4.text)], "Time From" : [str(self.input5.text)], "Time To" : [str(self.input6.text)]})
    self.L = pd.DataFrame(staff)

    self.input1.text = ''
    self.input2.text = ''
    self.input3.text = ''
    self.input4.text = ''
    self.input5.text = ''
    self.input6.text = ''

    print(self.L)
    with pd.ExcelWriter('staff.xlsx') as writer:
        self.L.to_excel(writer)

class Info(Screen): pass

class WindowManager(ScreenManager): pass

kv = Builder.load_file('window.kv')

class MyLayout(Widget):

class WindowApp(App): def build(self): return kv

if name == 'main': WindowApp().run()

And here is my kv file:

Any help will be appreciated.

Answer 1

The error you're getting can mean multiple things.

Are you trying to open a directory?

If so, don't do it. It will most likely result in the error you mentioned.

Is the file you are trying to opened anywhere else?

You may have to close it, for python to open it. You probably have experienced this before when trying to delete a file in the explorer, that is opened somewhere else. Windows won't let you do this. Check whether the file in question is opened before trying to access it.
