PythonTkinter按鈕洗掉 -有解無憂

我正在為自己做一個財務計劃，我在這一點上卡了一整天，我已經嘗試了很多解決方案，但對我來說并不奏效，所以我決定尋求幫助。

編輯。我把程式和資料庫連接起來了，在這部分我試圖進行 "分期付款"--檢查我是否支付了該月的專案。我提取了這個問題所需的幾行代碼，并重新命名了大部分變數，這樣至少可以讓你們有點了解，因為我是初學者，我在空閑時間為自己制作程式，抱歉，我犯了錯誤。

痛點。如果從串列中選擇的付款是在最后一期（例如4/4），我想做一個函式，并將其系結在同一個按鈕 "Pay selected "上，這將破壞持有付款名稱標簽的那個按鈕。我設法把它從資料庫中洗掉，但在程式重新啟動之前，按鈕不會消失，因為它不會被創建，因為它已經不在資料庫中了，但我想在最后一次付款完成后立即洗掉它。對我來說，解釋這個問題真的很復雜，因為我的英語不是很好。我發布了我的原始程式的視頻，這樣你們就可以理解我想要完成的任務。

你可以使用下面的代碼 :

import tkinter as tk

i = 0
def click（）。
    global i
    if i > 4:
        btn.destroy()
    else:
        i  = 1: btn.destroy()

root = tk.Tk()

btn = tk.Button(root, text="test", command=click)
btn.pack()

root.mainloop()

uj5u.com熱心網友回復：

這部分不需要幫助了，我只是用一個字典成功地做到了。這是第一部分，我把按鈕ID作為值加入到按鈕文本作為鍵

。

for opis in self.lista_opisa_rata。
    function = lambda x=opis: self.get_description(x)
    rata_button = Button(self.onr_top, text=opis, width=10, command=function)
    rata_button.grid(row=row, column=column, padx=5, pady=5)
    self.dict_for_buttons[opis] = rata_button

這是第二部分，我通過匹配標簽描述名稱和按鈕名稱來洗掉按鈕，并從字典中提取ID，通過ID洗掉按鈕。

def pay_selected（self）。
    p_description = self.onr_oznacena_rata_txt.cget("text"/span>)
    num_of_installments = self.onr_broj_rata_txt.cget("text"/span>).split("/")
    if int(num_of_installments[0])   1 >。 = int(num_of_installments[1]) 。
        c.execute('DELETE FROM OTPLATA_NA_RATE WHERE Opis = ?',(p_description,) )
        conn.commit()
        btn_to_del = self.dict_for_buttons[p_description] 。
        btn_to_del.destroy()
        self.dict_for_buttons.pop(p_description)

作業完美，但現在又發生了一個錯誤。無論如何，感謝你的幫助，如果我不能單獨解決這個問題，我會再次詢問！
