Python 合并文件夹下所有的Excel文件

打开windows窗口选择文件( askopenfilename( ) ) 或文件夹 ( askdirectory() )，以下代码是打开文件夹和文件的示例。

import tkinter.filedialog as tkFD

def __init__(self, root):
    self.ext1 = Button(self.frame[1], text="选择文件", command=self.openfile,width = 10)
        self.ext1.pack(side = LEFT, padx = 2,pady = 10)
        self.txt = Text(self.frame[1],height = 1,width = 80)
        self.txt.pack(side = LEFT, padx = 2,pady = 10)

        self.ext3 = Button(self.frame[3], text="选择根目录", command=self.opendir,width = 10)
        self.ext3.pack(side = LEFT, padx = 2,pady = 10)       
        self.path = Text(self.frame[3],height = 1,width = 40)
        self.path.pack(side = LEFT, padx = 2,pady = 10)

def openfile(self):
        self.filename=tkFD.askopenfilename(filetypes=[("Excel 工作簿", ".xls")])
        self.txt.delete(1.0,END)
        self.txt.insert(1.0,self.filename)
   
def opendir(self):
        self.pathname=tkFD.askdirectory()
        self.path.delete(1.0,END)
        self.path.insert(1.0,self.pathname)

同一个文件夹存在数量众多的Excel文件，比如某次活动邮件发送的Excel报名文件、各类记录等，需要手动对记录进行一条条的复制粘贴合并，快速的合并方式是通过pandas读取文件夹下的所有的Excel文件，然后统一合并。
