无法在 .write 函数中提供动态名称

Question

我使用 ttinker 给出导出文件的路径，然后尝试为输出文件提供动态名称，MRBTS 是一个不断变化的变量

问题是有时我能够将文件保存在给定目录中，但文件名会自动更改为目录名，我认为已使用的 filedialog.askdirectory() 中存在问题，有人可以指导吗？

Regen.configure(bg="grey")

Regen.geometry("300x300+500+200")

mylabel1=Label(text="VIL Regen Tool",fg="orange",bg="grey",font="Times 15 bold").pack()

mylabel1=Label(text="Developed by Sushanto Banerjee",fg="orange",bg="grey",font="Times 15 bold").place(x=10,y=100)

def xml_import():

    global xml_file

    xml_file=filedialog.askopenfile(filetypes=[("XML files","*.xml")])

    label1=Label(text="XML Backup Imported").place(x=100,y=240)

def excel_import():

    global excel_file

    excel_file=filedialog.askopenfilename(filetypes=[("Excel files","*.xlsx")])

    label2=Label(text="IP Plan Imported").place(x=120,y=270)

def export():

    global export_dir

    export_dir=filedialog.askdirectory()

    a=filedialog.

    mess=messagebox.showinfo(title="XML Generated",message="XMl generated")

    command=Regen.destroy()

    

button=Button(text="Import XML Backup",width=30,command=xml_import).pack()

button=Button(text="Import Excel IP Plan",width=30,command=excel_import).pack()

button=Button(text="Generate",width=30,command=export).pack()

Regen.mainloop()

                mytree.write( export_dir + str(MRBTS) +'_IPV6.xml',encoding='UTF-8')

我认为你的问题就在这里：export_dir + str(MRBTS) +'_IPV6.xml'askdirectory()不包括尾部斜杠。你真正想要的是：f'{export_dir}\{MRBTS}_IPV6.xml'然而，更清洁的方法如下所示：from tkinter import Tk, filedialogfrom os import pathroot = Tk()root.geometry('800x600')root.title("Test")&nbsp; &nbsp;#with one function handling all the save logic#~it becomes harder to make mistakes and easier to find themdef save_utf8(filename, data):&nbsp; &nbsp; folder&nbsp; &nbsp;= filedialog.askdirectory()&nbsp; &nbsp; filepath = path.join(folder, filename)&nbsp; &nbsp; with open(filepath, 'wb') as f:&nbsp; &nbsp; &nbsp; &nbsp; f.write(data.encode('utf-8'))&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;#represents some data that your app concoctedMRBTS&nbsp; &nbsp;= 'blahblah'xmldata = '<blah>BLAH</blah><blah>BLAH</blah><blah>BLAH</blah>'#utilize the save functionsave_utf8(f'{MRBTS}_IPV6.xml', xmldata)root.mainloop()
