继续打印文本到Python的下一行

Question

我有一行文字，我希望通过剪切结束并将其打印到下一行来使其更好看。我正在使用Tkinter并试图使Label使用3行而不是1，因为文本太长而无法显示。

label4Text.set("0.0.0.0 This subnet mask is non-routable as there is no network portion")

看起来像这样：

[0.0.0.0 This subnet mask is non-routable as there is no network portion]

我希望它看起来像这样：

[0.0.0.0

This subnet mask is non-routable

There is no network portion]

如何实现这一目标？

Answer 1

使用\n，例如：

label4Text.set("0.0.0.0\nThis subnet mask is non-routable\nas there is no network portion")

演示：

In [4]: s = "0.0.0.0 \nThis subnet mask is non-routable\nThere is no network portion"

In [5]: print s
0.0.0.0 
This subnet mask is non-routable
There is no network portion
