Prompting for File Input Without a GUI: A Quick and Easy Solution

In Python, you can encounter scenarios where you need to request file input within a script without presenting a user interface. The standard library offers a convenient solution to this: Tkinter, a GUI module that can assist in displaying file selection dialogs.

Consider the following code snippet:

<code class="python">import tkFileDialog
file_path_string = tkFileDialog.askopenfilename()</code>

While this code provides file selection functionality, it leaves an undesired empty frame visible on the screen. To resolve this, Tkinter provides an option to hide the root window by utilizing the withdraw method:

<code class="python">import tkinter as tk
from tkinter import filedialog

root = tk.Tk()
root.withdraw()

file_path = filedialog.askopenfilename()</code>

Alternatively, for Python 2 compatibility, the following variant can be used:

<code class="python">import Tkinter, tkFileDialog

root = Tkinter.Tk()
root.withdraw()

file_path = tkFileDialog.askopenfilename()</code>

With these modifications, the file selection dialog appears without any additional GUI elements, offering a quick and easy way to prompt for file input within a script.
