pythontkinter：从ttk.Combobox获取值

我在SQLite数据库（employee_position）中有职位数据。此外，它还获取位置的数据：

self.employee\u position=员工信息[0][8]

但是，我无法插入数据。如何将数据插入组合框

它适用于其他字段，如输入：

    #Entry
    self.email_entry.insert(0, self.employee_email)
    self.email_entry.config(state = 'disabled')  

    # Position
    self.available = self.employee_position

    self.position_lbl = Label(self.centerFrame, text = 'Position:', fg = '#b3b3b3', bg = '#121212')
    self.position_lbl.grid(row = 7, column = 0, sticky = W, columnspan = 2, padx = 5)

    self.position = ttk.Combobox(self.centerFrame, values=self.available, width = 27)

    self.position.config(state = 'disabled')
    self.position.grid(row = 7, column = 1, sticky = W, columnspan = 2, pady = 5)

解决方案： #位置

    self.available = [self.employee_position]
    self.position_lbl = Label(self.centerFrame, text = 'Position:', fg = '#b3b3b3', bg = '#121212')
    self.position_lbl.grid(row = 7, column = 0, sticky = W, columnspan = 2, padx = 5)

    self.position = ttk.Combobox(self.centerFrame, values=(self.available), width = 27)
    self.position.set(self.employee_position)
    self.position.config(state = 'disabled')
    self.position.grid(row = 7, column = 1, sticky = W, columnspan = 2, pady = 5)

self.employee\u position

的类型是什么？我想知道您为什么不使用

Label

而不是

Combobox

作为

self.position

，因为只有一项？
