Python 为什么每行上都重复第一个SQL行？

我不确定我错过了什么。我正在为前10行运行SQL查询。我正在将它们输出到Tkinter Entrys。为什么每个条目（如self.output1和self.output2）中只显示第一个SQL行？ 我希望每个SQL行显示在每个Tkinter条目中

问题是输入小部件选项

text

只是

textvariable

的缩写；条目小部件没有

文本

选项。这意味着每个小部件共享相同的textvariable。因为它们都绑定到相同的

textvariable

上，所以将共享相同的值。因此，当您在其中插入文本时，它将被插入到所有文本中

---

解决方案是从您创建

条目

小部件的每个位置删除

text='

。
