尝试制作一个税收计算器，我一直在努力研究如何制作它，以便可以使用输入框中的输入和确认输入的按钮来更改变量（工资）。我不确定这是我的布局还是我遗漏了一些东西（可能很明显）。
我确信这与错误代码的命令有关： 类型错误：int() 参数必须是字符串、类似字节的对象或实数，而不是“Entry” 运行时就会出现。
如果在代码本身中更改工资变量，那么一切似乎都会加起来，所以这只是如何将它们结合在一起。
这是我到目前为止所做的代码：

gross_wage_title = tk.Label(text="Enter gross wage: £")
tax_band_title = tk.Label(text="Your Tax band is: ")
taxation_title = tk.Label(text="Amount to pay in tax: £")
yearly_net_wage_title = tk.Label(text="Your yearly net wage will be: £")

我想要的是将薪水添加到 Entry 小部件中，然后在按下“计算”按钮时将薪水变量更改为该数字。
您需要将主块中的计算移至

请注意，在创建小部件时最好指定它们的主/父部件。
