在Tkinter中重命名文件名

Question

所以我试图通过Tkinter创建一个程序，用户可以通过文件系统进行操作。我有其他不起作用的按钮的单独代码，但重命名按钮让我很难过。我怎么能在这段代码中关闭filedialog？

这是我的代码。

from tkinter import *
import sys,glob,time,os
from tkinter import filedialog

def dir2():
    global direc
    direc=filedialog.askdirectory(initialdir="/",title="Choose directory")
    dire1.config(text=direc)
    print(direc)
    mainloop()

def cancelr():
    rrf.destroy()
    root.deiconify()

def rnf():
    name1=os.path.basename(rpath.name)
    filee=None
    for filee in glob.glob(name1):
        if os.path.isdir(filee)==False:
            os.rename(name1,nfn.get())
            print("done")
        elif file == None:
            print("nothing")

def rf():
    global fn
    global rrf
    global rpath
    global name1
    nfn=StringVar()
    nfn.set(" ")
    rpath=filedialog.askopenfile(initialdir=direc,title="Rename a file")
    os.chdir(direc)
    rrf=Toplevel(root)
    root.iconify()
    rrf.geometry('350x100+500+200')
    body=Frame(rrf)
    body.pack()
    Label(body,text="Enter new file name: ",font=("Arial",15)).pack()
    nfname=Entry(body,textvariable=nfn, width=50 ).pack()
    body2=Frame(rrf)
    body2.pack()
    Button(body2,text="Done", font=   ("Arial",10),command=rnf).grid(row=0,column=0,padx=5,pady=4)
    Button(body2,text="Cancel",font=("Arial",10),command=cancelr).grid(row=0,column=1,padx=5,pady=4)
    mainloop()

 def creation():
    os.chdir(direc)
    fname=fn.get()
    file=open(fname,"w")
    file.close
    done=messagebox.askyesno("File created!","Continue creating file?")
    if done==True:
        return
    else:
        crf.destroy()
        root.deiconify()

def cancelc():
    crf.destroy()
    root.deiconify()
def df():
    dfname=filedialog.askopenfilename(initialdir=direc,title="Choose a  file")
    done=messagebox.askyesno("Confirm","Delete file?")
    if done==True:
        os.remove(dfname)
        messagebox.showinfo("Success!","File deleted")
    else:
        return
def cf():
    global fn
    global crf
    fn=StringVar()
    fn.set(" ")
    crf=Toplevel(root)
    root.iconify()
    crf.geometry('350x100+500+200')         
    body=Frame(crf)
    body.pack()
