我有以下代码，用于打开GUI，允许我从指定的路径浏览文件，然后单击提交按钮后，网页将从xlsx文件和网页的输出在线填充再次存储在输出xlsx文件中。我的代码完成了所有目标。但是有一个问题 - 我在编辑小部件旁边有一个浏览按钮，它允许我浏览文件路径以在GUI中获取输入文件。现在我按下浏览按钮的那一刻，虽然它获取文件但它将文件路径放在浏览按钮旁边，如下所示：enter image description here
代码是这样的：

master.title("Webscrapper")

代码的一部分：
self.browse_file=Button(master,text="Browse",command=self.file_found)
self.browse_file.grid(row=0,column=2,sticky=E)
调用file_found（）浏览路径以获取文件，但这不会填充
self.path_field = Entry(master)
self.path_field.grid(row=0,column=1,sticky=W)
self.path_field是应该由浏览按钮获取的文件路径填充的条目小部件。
好;据我所知，你想要条目中的文件路径，而不是单独的标签。但是在你的代码中你把它放在一个单独的标签而不是在条目中...
以下是如何将路径放入条目的示例：
def file_found(self):
self.path_browse=fd.askopenfilename(initialdir="/",title="Select A file",
filetype=(("Excel Workbook","*.xlsx"),("All Files","*.*")))
self.path_field.delete(0,END) # Remove any previous content
self.path_field.insert(0,self.path_browse) # Insert new content
我不清楚你想要用这条线完成什么：
self.path_field.bind("<Return>",self.path_browse)
它将path_field条目中的Return绑定到变量...
