def add_laytime(self):
        self.variaveis()
        self.conecta_bd()

        self.cursor.execute("""

        for n in self.listacli.selection():

    def lista_frame2(self):
        self.listacli = ttk.Treeview(self.frame_2, height=3,
                                     column=("col1", "col2", "col12", "col15"))
        self.listacli.heading("#0", text="")
        self.listacli.heading("#1", text="Vessel")
        self.listacli.heading("#2", text="Commodity")
        self.listacli.heading("#3", text="Allowed")
        self.listacli.heading("#4", text="Estimated ($)")
        
        self.listacli.column("#0", width=1)
        self.listacli.column("#1", width=50)
        self.listacli.column("#2", width=200)
        self.listacli.column("#3", width=125)
        self.listacli.column("#4", width=125)
        self.listacli.place(relx=0.01, rely=0.1, relwidth=0.95, relheight=0.85)

我有一个需要填写的表格，当我点击添加信息并存储在frame2中时，只有船舶和商品被正确保存。 “allowed”正在接收“dayoper”的值，“estimated_value”正在接收权重。换句话说，前两个是对的，后两个是错的。

Answer 1

我编写了最少的工作代码来测试它，我发现了两个问题。
但两者都会生成错误消息，您应该在控制台/终端中看到该消息。

1. 你应该只有 4 个变量

col1, col2, col3, col4 = self.listacli.item(n, 'values')

2. 您使用变量

   col12

   和

   col15

   但您需要

   col3

   和

   col4

self.allowed_value.insert(END, col3)    # col12
self.estimated_value.insert(END, col4)  # col15
