如何将多个文本字段输入及其功能连接到 tkinter python 中的一个按钮？

Question

我有这个问题，我需要使用在这种情况下为计算的唯一按钮来显示其他函数的值。第一个函数显示，但另一个函数在使用其文本输入字段时不显示。

我尝试过复制，使用相同的代码但希望更改名称。

import tkinter as tk
from functools import partial

n_num = list(map(int, input('Enter mean numbers: ').split()))
n = len(n_num)

get_sum = sum(n_num)
mean = get_sum / n

print("Mean / Average is: " + str(mean))



def mean_result (label_mean_result,num):
    n_num = list(map(int,num.get()))
    n = len(n_num)

    get_sum = sum(n_num)
    mean = get_sum /n
    label_mean_result.config(text=f"Mean Result = {mean}")
    return


def median_result (label_median_result,num):
    n_num = list(map(int,num.get()))
    n = len(n_num)
    n_num.sort()

    if n % 2 == 0:
        median1 = n_num[n // 2]
        median2 = n_num[n // 2 - 1]
        median = (median1 + median2) / 2
    else:
        median = n_num[n // 2]
        label_median_result.config(text=f"Median Result = {median}")
    #print("Median is: " + str(median))
    return


root = tk.Tk()
root.geometry('400x200+100+200')

root.title('Final program')


## Mean input and output
meanInput = tk.StringVar()

labelMean = tk.Label(root, text="Mean input:").grid(row=1, column=0)

labelResult = tk.Label(root)

labelResult.grid(row=7, column=2)

entryNum1 = tk.Entry(root, textvariable=meanInput).grid(row=1, column=2)

mean_result = partial(mean_result, labelResult, meanInput)

buttonCal = tk.Button(root, text="Calculate", command=mean_result).grid(row=3, column=0)

#####

medianInput = tk.StringVar()

labelMedian = tk.Label(root, text="Median input:").grid(row=2, column=0)

labelResult2 = tk.Label(root)

labelResult2.grid(row=7, column=2)

entryNum2 = tk.Entry(root, textvariable=medianInput).grid(row=2, column=2)

median_result= partial(median_result, labelResult2, medianInput)

root.mainloop()

在这种情况下，当我使用唯一的按钮（计算）从两个函数中输入值时，我期望得到结果。因此，我很想知道如何将多个功能连接到一个按钮并显示它们的结果。例如，第一个函数显示“平均函数”结果；单击“计算”按钮时，第二个函数“中位数”未连接并显示。

现在这可能与您所拥有的有很大不同，但这是可扩展的，您可以根据自己的兴趣抽象事物。我只是觉得它更具可读性

您在示例中计算了中位数，只是认为使用统计模块会更简洁。意思已经很干净了

我希望这会有所帮助:)
