How I Made A Small Login With Python And Tkinter 🐍

Python is a versatile and powerful programming language that can be used to create a wide variety of applications. Among its many libraries, Tkinter stands out as a popular choice for creating graphical user interfaces (GUIs). In this article, I will walk you through the process of creating a small login application using Python and Tkinter.

Set up your environment

Before you begin, make sure you have Python installed on your system. You can download it from the official website and follow the installation instructions. Once Python is installed, you can proceed to install Tkinter by using the following command:

pip install tk

Create the login form

First, import the necessary modules in your Python file:


import tkinter as tk
from tkinter import messagebox


Then, create the main window for your application:


root = tk.Tk()
root.title("Login Form")


Next, add the necessary labels and entry fields for the username and password:


username_label = tk.Label(root, text="Username")
username_label.pack()
username_entry = tk.Entry(root)
username_entry.pack()

password_label = tk.Label(root, text="Password")
password_label.pack()
password_entry = tk.Entry(root, show="*")
password_entry.pack()


Implement the login functionality

Now, create a function that will be called when the user clicks the login button:


def login():
username = username_entry.get()
password = password_entry.get()

if username == "admin" and password == "password":
messagebox.showinfo("Success", "Welcome, admin!")
else:
messagebox.showerror("Error", "Invalid username or password")


Finally, add a button to the window and associate the login function with it:


login_button = tk.Button(root, text="Login", command=login)
login_button.pack()


Run the application

Finally, start the Tkinter event loop to display the window and wait for user input:


root.mainloop()


That’s it! You have now created a small login application using Python and Tkinter. Feel free to customize the look and feel of the application to match your preferences, and add additional features such as user authentication and error handling. Happy coding!
