如何在 tkinter GUI python 中将结果从 int 更改为 double？试过投射但没有用

Question

下面是我的代码，结果始终是不带小数的整数，如何将其更改为双精度或带小数的数字？

我试过投射但没有成功。


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 = "Result = %d" % float(mean))
    return



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

root.title('Final program')

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)

我希望输出是带小数的数字，而不是整数。

您不必将其转换为 float。

只需使用字符串格式：

label_mean_result.config(text="Result = {}".format(mean))

或 f 字符串：

label_mean_result.config(text=f"Result = {mean}")
