我有以下代码，其目的是打开一个GUI，该GUI允许我从指定的路径浏览文件，然后单击“提交”按钮，然后从xlsx文件和该文件的输出在线填充网页。网页再次存储在输出xlsx文件中。 我的代码实现了所有目标。但是有一个问题-我在编辑小部件旁边有一个浏览按钮，它使我可以浏览文件路径以在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，但是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：

from tkinter import messagebox as msg
from tkinter import filedialog as fd

部分代码：
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（），它会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)
其中self.path_field是条目小部件，应由浏览按钮获得的文件路径填充。
答案 0 :(得分：1)
好吧；据我了解，您希望文件路径位于条目中，而不是在单独的Label中。但是在您的代码中，您将其放在单独的标签中，而不是在条目中...
这是一个如何在条目中放置路径的示例：
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
我不太清楚您要达到的目标：
self.path_field.bind("<Return>",self.path_browse)
它将path_field条目中的Return绑定到变量...
