首先,对不起这个模糊的标题。我正在制作一个显示时间,获取天气和新闻的python应用程序。现在,当我通过tkinter标签打印新闻时,它将新闻标题打印在单独的一行上但在中心。如果我尝试指定.pack(side = LEFT)几何形状,它将移至左侧,但所有标题均以字符串而不是换行符的形式显示。我试图通过'\ n'添加新行,甚至用回车符'\ n'都无效。请帮我解决这个问题。附加下面的代码。
P.s我无法获得与For循环一起使用的消息,因此我手动打印了阵列。

首先:我删除了代码中的图片,因为我没有这些图片,我想浪费时间搜索可用作替换的图片。
如果您为标签设置了不同的颜色,那么您会看到宽度有所不同-它们使用的是文本宽度。
如果您使用
self.headline1_lb.pack(fill='x')
然后它们将使用相同的宽度,但文本仍居中。
如果您使用
Label(..., anchor='w')
然后它将文本移到左侧。
如果要在标签文本中插入多行,则可能还需要
Label(..., anchor='w', justify='left')
如果要使用整个窗口宽度的文本,则必须使用fill='x'
self.news.pack(side=BOTTOM, anchor='s', fill='x')
之后,您可以再次设置black
