Visual Studio Code – GUI isn't showing up after running python code

I’m building an Image to PDF converter app using python. When I run the code in the terminal the UI doesn’t appear. Here is the code:

`import tkinter as tk
 from tkinter import filedialog, messagebox
 import os

 class ImageToPdfConverter:
    def __init__(self, root):
        self.root = root
        self.image_paths = []
        self.output_pdf_name = tk.StringVar()
        self.selected_image_listbox = tk.Listbox(root, selectmode=tk.MULTIPLE)

        self.initialize_ui()

    def initialize_ui(self):
        title_label = tk.Label(self.root, text = "Image to PDF Converter", font=("Helvetica", 16,
        "bold"))
        title_label.pack(pady=10)

def main():
    root = tk.Tk()
    root.title("Image to PDF")
    root.geometry("400x600")
    root.mainloop()

    if __name__== "__main__":
        main()`

When I click "Run Python File in Terminal", it runs however the UI does not show up.

    The indentation of the main function at the end of the code is incorrect and should be changed to the following

    def main():
    root = tk.Tk()
    root.title("Image to PDF")
    root.geometry("400x600")
    root.mainloop()

if __name__== "__main__":
    main()

    your code looks just fine but at the end the indentation of
    if __name__== "__main__": main()
    is incorrect.

    Here’s your fixed code that will generate the tkinter GUI:

    import tkinter as tk
from tkinter import filedialog, messagebox
import os

class ImageToPdfConverter:
    def __init__(self, root):
        self.root = root
        self.image_paths = []
        self.output_pdf_name = tk.StringVar()
        self.selected_image_listbox = tk.Listbox(root, selectmode=tk.MULTIPLE)

        self.initialize_ui()

    def initialize_ui(self):
        title_label = tk.Label(self.root, text = "Image to PDF Converter", font=("Helvetica", 16,
        "bold"))
        title_label.pack(pady=10)

def main():
    root = tk.Tk()
    root.title("Image to PDF")
    root.geometry("400x600")
    root.mainloop()

if __name__== "__main__":
    main()
