我为其他代码创建了一个名为clinic1.py的单独文件，并将其导入主页面。一切正常，但是当我点击添加新项目页面上的保存按钮时，会出现另一个窗口。
当我将所有代码放在主页上时，小窗口不会出现。 我找不到什么导致另一个窗口显示在另一个文件中。
这是我的主页：
<nav>
<div class="panel center">
<ul>
<li><a href="Home.html">Home</a></li> <!--All the pages on the website-->
<li><a href="SerieA_Tables.html">Table</a></li>
<li><a href="News.html">News</a></li>
<li><a href="Teams.html">Teams</a>
<ul>
<li><a href = "#">Juventus</a></li>
<li><a href = "#">AC Milan</a></li>
<li><a href = "#">Torino</a></li>
</ul>
</li>
<li><a href="About.html">About</a></li>
</ul>
</div>
</nav>这是我在主页面导入的第二个文件，我保存为clin1.py

答案 0 :(得分：2)
这两个文件都有这行代码：
b()每次执行此操作时，您都会获得另一个根窗口。 tkinter应用程序需要一次只运行一个root = Tk()
个实例。
您需要从clin1.py中删除最后两行。您还需要将Tk的引用传递给来自clin1.py的任何需要它的方法。
