在Python编辑器中锁定文本？并在边界内锁定Python中的文本？

Question

我已经在我的代码中写了一些Lorum Ipsum填充词来测试这些词，但是我有两个明显的问题，即单词不能进入另一行。我对代码编辑器的整洁性和程序本身都有问题。下面我将写下我目前在编辑器和程序中遇到的所有问题

编辑器问题：我不知道如何让我的编辑器将这些词锁定在编辑器的边界内，而不是进入一些非常长的行，我无法向左滚动以返回到原始代码。我在编辑器上找不到任何能把单词推回到编辑器左边的东西。我使用的是空闲编辑器，我还找不到一个将单词推回到左边的函数，但是当我处理HTML时，我可以使用Notepad++很好地找到它。我不知道如何使用Notepad++来编写Python代码，宁愿继续使用空闲编辑器

程序GUI问题：在我制作的Tkinter GUI中，Lorum Ipsum单词在960px宽的整洁程序中没有锁定在一起。我不明白怎么修。当我尝试使用“.grid”函数而不是“.pack”函数时，如果我尝试在它下面放置一个图形，则会出现错误。当我尝试“.pack”函数时，它不会出错，但是单词并没有像预期的那样锁定在程序的边界内，相反，单词只是在一行中居中

import tkinter as tk
from tkinter import *

root = tk.Tk()
root.geometry("960x600")

label_toptitle = tk.Label(root,
                      text="Program Name",
                      font=(None, 40),
)
label_toptitle.pack(side="top", fill="x")

label_desc = Label(root,
               text="Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa.
