下拉菜单 python

Question

我刚开始学习 tkinter，我的第二个下拉菜单有问题。

from tkinter import *
from Bmi import *
from Calories import *
root = Tk()
root.title('Gym')
root.configure(background='#C7BBB8')

#Drop Down Boxes
options = [
    "Man",
    "Woman"
]
#Define sex
sex = StringVar()
sex.set(options[0])
sexLabel = Label(root, text="| Sex |", bg='#C7BBB8')
sexLabel.grid(row=0, column=4)
#Define drop menu
drop = OptionMenu(root, sex, *options)
drop.config(width=15)
drop.grid(row=1, column=4)


def getData2():
    caloric()


#Define BMI button
getButton = Button(root, text="Check your BMI", command=getData)
getButton.grid(row=3, column=1, columnspan=4)

#Define KCAL button
getButton = Button(root, text="Check calories you burn", command=getData2)
getButton.grid(row=4, column=1, columnspan=4)


#Choose if you want to add or decay calories
#Choose your life style b4 .amr


def caloric():
    root = Tk()
    root.configure(background='#C7BBB8')

    # Lifestyle menu
    options = [
        "Sedentary (little or no exercise)",
        "Lightly active (exercise 1–3 days/week)",
        "Moderately active (exercise 3–5 days/week)",
        "Active (exercise 6–7 days/week)",
        "Very active (hard exercise 6–7 days/week)"
       ]

    # Style label and drop list declare
    style = StringVar()
    style.set(options[0])
    styleLabel = Label(root)
    styleLabel.grid(row=3, column=4)
    drop = OptionMenu(root, style, *options)
    # drop2.config(width=15)
    drop.grid(row=4, column=0)

    #Variables
    lStyle = style.get()

    p1 = Calories(lName, int_lHeight, int_lWeight, int_lAge, lSex)
    p2 = p1.amr()

    testLabel = Label(root, text=lName + " " + p2)
    testLabel.grid(row=1, column=0)

    #Additional options
    testLabel = Label(root, text="\nChoose your lifestyle for better calculations")
    testLabel.grid(row=2, column=0)

    root.mainloop()

root.mainloop()

我正在尝试创建分隔 window 当您可以选择您的生活方式时（从第 84 行开始），但它不起作用，尽管第一个下拉菜单工作正常。也许 window 声明有问题（？），但我不知道如何进行不同的设置。

Answer 1

对于热量方法稍微更改分配值，因为 root 已经在使用所以最好尝试

new_win = Toplevel()
new_win .configure(background='#C7BBB8')

并将卡路里 window 更改为 new_win，这样它将创建一个弹出窗口 window 第二个选项
