optionMenu沒有出現在視窗tkinter中

我對 python 和 tkinter 很陌生。我正在嘗試構建下面的 GUI 界面，這是一個護膚程式，它將根據從 4 個下拉選單中選擇的結果推薦產品。最后一個按鈕 - 幫助將顯示聯系資訊。

我正處于起步階段，無法顯示年齡的第一個選項選單。任何人都可以解釋一下這個原因嗎？我該如何做到這一點，以便將年齡、皮膚型別、主要皮膚問題和清潔美容的答案組合起來，從而產生由于組合而推薦的產品？

import tkinter as tk

age_menu = [
"<=18", 
"19 - 25", 
"25 - 34", 
"35 - 45"
]

uj5u.com熱心網友回復：

所以我遇到的第一個問題是格式化，所以我重寫了它以遵循

此示例將顯示您想要我在評論中的意思。我洗掉了很多width引數，因為你真的不需要它。我還添加了root.resizable(False, False)設定永久視窗大小。有時這對于簡單的 GUI 來說更容易。我還洗掉了行和列配置，因為我控制了視窗大小。我也對視窗大小進行了微調。

age_menu = [
    "<=18",

root = tk.Tk()
root.geometry("750x450") 
root.title("SAVE MY SKIN")
root.configure(bg="#32402f")
root.resizable(False, False) # stops the user from maximizing the window 

#might not need or want the row and column config this way
#root.grid_rowconfigure(0, weight=1)  
#root.grid_columnconfigure(0, weight=1)

greeting = tk.Label(root, text="Hello!", fg="#faf2e9", bg="#32402f", font=("Courier", 20, "bold"), anchor="w",
                    padx=30)
