如何使用 os.path.basename 不带 '> 扩展名获取文件名

Question

I'm trying to get a string that contains only the filename. I know you can use os.path.basename to get the just the filename without the pathway. However, this still keeps the '> portion of the name. I want to only get the filename, without anything else.

IE

<_io.BufferedReader name='C:/Users/Sams PC/Desktop/file.txt'>
#printout using os.path.basename
file.txt'>
##Desired
file.txt

For some context of what I'm using to get this, this is my script (its using tkinter ):

def browse():
    result=tk.filedialog.askopenfile(parent=root,mode='rb',title='Choose a file')
    return result
print(browse())
print(os.path.basename(str(browse())))

Answer 1

You need to use filedialog.askopenfilename instead of filedialog.askopenfile to obtain the filename without side effects (like opening a file). This returns the full path; you can extract the filename from the fullpath using os.path.basename

import os
import tkinter as tk
from tkinter import filedialog

def browse():
    root = tk.Tk()
    root.withdraw()
    fullpath = filedialog.askopenfilename(parent=root, title='Choose a file')
    filename = os.path.basename(fullpath)
    root.destroy()

    return filename

print(browse())
