TypeError: value_list() takes 1 positional argument but 2 were given

问题遇到的现象和发生背景

我在尝试做一个计算器，尝试把算出的值存到一个字典中，以便之后使用。

运行结果及详细报错内容
Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python3.8/tkinter/__init__.py", line 1892, in __call__
    return self.func(*args)
TypeError: value_list() takes 1 positional argument but 2 were given
[Finished in 12.3s]
以下为value.py
from tkinter import *
from tkinter.messagebox import *

class calc(object):
    def __init__(self, root):
         super(calc, self).__init__()
         self.root = root
         ---snip---
         self.res_show()
         valueList = {} #空字典

    def delta_t_calc(self,**valueList):
        self.valueList = valueList
        try:
            self.t_in = float(self.inEntry.get())    
            self.t_out = float(self.outEntry.get())
        except:
            return showwarning('ValueError:','Please enter numbers')
        self.delta_t = self.t_in - self.t_out
        self.value1 = {'delta_t':'self.delta_t'}
        return valueList.update(self.value1)

    #出错的地方：（
    def value_list(self,**valueList):
        print (valueList['delta_t'])

    def res_show(self):
        self.res = Button(self.root,text='calculate \n now',
            relief="groove",bg="#393939",fg="white")
        self.res.grid(row=2,column=0,sticky=E+W)
        self.res.bind("",self.value_list)
run.py
root = Tk()
cal_settings = Settings()
root.title(cal_settings.title)
root.geometry(cal_settings.geometry)
root.configure(bg="#484848")

runner = calc(root)

root.mainloop()
我的解答思路和尝试过的方法

我以为是字典的原因，于是给加了**valueList. 但好像不是这样的。

run.py没有贴出完整的

run.py 完整的

from tkinter import *
from tkinter import ttk 
from settings import Settings
from value import calc

root = Tk()
cal_settings = Settings()
root.title(cal_settings.title)
root.geometry(cal_settings.geometry)
root.configure(bg="#484848")

runner = calc(root)

root.mainloop()
