Choosing a file in Python with simple Dialog

This worked for me

Reference : https://www.youtube.com/watch?v=H71ts4XxWYU

import  tkinter as tk
from tkinter import filedialog
root = tk.Tk()
root.withdraw()
file_path = filedialog.askopenfilename()
print(file_path)

I obtained much better results with wxPython than tkinter, as suggested in this answer to a later duplicate question:

https://stackoverflow.com/a/9319832

The wxPython version produced the file dialog that looked the same as the open file dialog from just about any other application on my OpenSUSE Tumbleweed installation with the xfce desktop, whereas tkinter produced something cramped and hard to read with an unfamiliar side-scrolling interface.

The suggested root.withdraw() (also here) hides the window instead of deleting it, and was causing problems when using interactive console in VS Code ("duplicate execution" error).

Below two snippets to return the file path in "Open" or "Save As" (python 3 on Windows):

import tkinter as tk
from tkinter import filedialog

filetypes = (
    ('Text files', '*.TXT'),
    ('All files', '*.*'),
)

# open-file dialog
root = tk.Tk()
filename = tk.filedialog.askopenfilename(
    title='Select a file...',
    filetypes=filetypes,
)
root.destroy()
print(filename)

# save-as dialog
root = tk.Tk()
filename = tk.filedialog.asksaveasfilename(
    title='Save as...',
    filetypes=filetypes,
    defaultextension='.txt'
)
root.destroy()
print(filename)
# filename == 'path/to/myfilename.txt' if you type 'myfilename'
# filename == 'path/to/myfilename.abc' if you type 'myfilename.abc'

Here is a simple function to show a file chooser right in the terminal window. This method supports selecting multiple files or directories. This has the added benefit of running even in an environment where GUI is not supported.

from os.path import join,isdir
from pathlib import Path
from enquiries import choose,confirm

def dir_chooser(c_dir=getcwd(),selected_dirs=None,multiple=True) :
    '''
        This function shows a file chooser to select single or
        multiple directories.
    '''
    selected_dirs = selected_dirs if selected_dirs else set([])

    dirs = { item for item in listdir(c_dir) if isdir(join(c_dir, item)) }
    dirs = { item for item in dirs if join(c_dir,item) not in selected_dirs and item[0] != "." } # Remove item[0] != "." if you want to show hidde

    options = [ "Select This directory" ]
    options.extend(dirs)
    options.append("⬅")

    info = f"You have selected : \n {','.join(selected_dirs)} \n" if len(selected_dirs) > 0 else "\n"
    choise = choose(f"{info}You are in {c_dir}", options)

    if choise == options[0] :
        selected_dirs.add(c_dir)

        if multiple and confirm("Do you want to select more folders?") :
            return get_folders(Path(c_dir).parent,selected_dirs,multiple)

        return selected_dirs

    if choise == options[-1] :
        return get_folders(Path(c_dir).parent,selected_dirs,multiple)

    return get_folders(join(c_dir,choise),selected_dirs,multiple)

To install enquiers do,

pip install enquiries

Using Plyer you can get a native file picker on Windows, macOS, Linux, and even Android.

import plyer

plyer.filechooser.open_file()

There are two other methods, choose_dir and save_file. See details in the docs here.

I resolved all problem related to from tkinter import * from tkinter import filedialog

by just migrating from pycharm IDE to visual studio code IDE and every problem is solved.
