Automatic gui for python script with command line arguments

When working with Python scripts that require command line arguments, it can be helpful to have an automatic GUI to simplify the process. In this article, we will explore three different ways to achieve this using Python.

Option 1: Tkinter

Tkinter is a popular Python library for creating graphical user interfaces. It provides a set of tools and widgets that can be used to build a GUI for our Python script.

import tkinter as tk
from tkinter import filedialog

def open_file():
    file_path = filedialog.askopenfilename()
    # Do something with the file

root = tk.Tk()
button = tk.Button(root, text="Open File", command=open_file)


In this example, we create a simple GUI with a button that opens a file dialog when clicked. The selected file path can then be used in our Python script.

Option 2: PySimpleGUI

PySimpleGUI is another Python library that provides a simple and intuitive way to create GUIs. It is built on top of tkinter and offers a higher-level interface.

import PySimpleGUI as sg

layout = [[sg.Text('Select a file:'), sg.Input(), sg.FileBrowse()],
          [sg.Button('Open'), sg.Button('Cancel')]]

window = sg.Window('File Selector', layout)

while True:
    event, values =
    if event == sg.WINDOW_CLOSED or event == 'Cancel':
    elif event == 'Open':
        file_path = values[0]
        # Do something with the file


In this example, we define a layout using a list of lists. Each inner list represents a row in the GUI. We use various PySimpleGUI elements like Text, Input, FileBrowse, and Button to create the desired interface. The selected file path is then retrieved from the values dictionary.

Option 3: PyQt

PyQt is a Python binding for the Qt framework, which is a powerful and widely-used GUI toolkit. It provides a comprehensive set of tools for creating cross-platform applications with a native look and feel.

from PyQt5.QtWidgets import QApplication, QFileDialog, QPushButton, QVBoxLayout, QWidget

def open_file():
    file_dialog = QFileDialog()
    file_path = file_dialog.getOpenFileName()[0]
    # Do something with the file

app = QApplication([])
window = QWidget()
layout = QVBoxLayout()
button = QPushButton('Open File')

In this example, we create a QApplication and a QWidget to hold our GUI elements. We use a QVBoxLayout to arrange the elements vertically. The QPushButton is connected to the open_file function, which opens a file dialog and retrieves the selected file path.

After exploring these three options, it is clear that PySimpleGUI provides the simplest and most intuitive way to create a GUI for a Python script with command line arguments. It offers a higher-level interface compared to tkinter and PyQt, making it easier to define the layout and handle events. Therefore, PySimpleGUI is the recommended option for this particular task.
