我正在开发 Tkinter GUI.

I am working on a Tkinter GUI.

我想知道如何删除文本小部件末尾的换行符 (\n)?这让我的应用看起来很难看，我不想要这个.

I am wondering how can I remove newline character (\n) at the end of Text widget? It's making my App looking ugly I don't want this.

示例代码是:

from tkinter import *
from tkinter import ttk

window = Tk()
window.title('Advanced Calculator v0.9')
window.geometry('500x400')
window.resizable(False, False)

window.configure(background='black')

hist_t = Text(window, background='black', height='7', foreground='red', font='Verdana', highlightcolor='grey', highlightthickness=1, relief='solid')

Label(window, text='History:', background='black', foreground='red').pack(pady=3, anchor='w')

hist_t.pack(fill='x', padx=3)

hist_t.insert('end', '4 + 4 = 8\n2 + 2 = 4\n5 + 3 = 8\n10 + 13 = 23\n30 + 10 = 40\n12 + 8 = 20')

window.mainloop()

谢谢.

推荐答案

您的问题似乎不是任何额外的换行符，只是您将其配置为显示 7 行，但您只插入了 6 行.如果您设置高度为 6 你不会看到这个空行.

Your problem doesn't appear to be any extra newlines, it's simply that you configured it to show 7 lines but you're only inserting 6. If you set the height to 6 you won't see this blank line.
