Creating a Login Form for Apps Using Python: A Tkinter Project (#part1)

In this tutorial, we will be creating a login form for apps using Python and Tkinter. Tkinter is a commonly used GUI toolkit for Python, and it allows you to create windows, dialogs, and other graphical user interface components.

To start off, let’s create a new Python file and import the Tkinter module:

from tkinter import *

Next, we will create a new class called LoginForm that will represent our login form. We will define the init method that will initialize the window, labels, and entry fields for the username and password:

class LoginForm:
    def __init__(self, root):
        self.root = root
        self.root.title("Login Form")

        self.label_username = Label(root, text="Username")
        self.label_username.pack()

        self.entry_username = Entry(root)
        self.entry_username.pack()

        self.label_password = Label(root, text="Password")
        self.label_password.pack()

        self.entry_password = Entry(root, show="*")
        self.entry_password.pack()

Now, let’s create a new method called login that will be triggered when the user clicks on the "Login" button. This method will validate the username and password entered by the user:

def login(self):
    username = self.entry_username.get()
    password = self.entry_password.get()

    if username == "admin" and password == "password":
        print("Login successful")
    else:
        print("Login failed")

Next, we will create a button called "Login" that will trigger the login method when clicked:

self.button_login = Button(root, text="Login", command=self.login)
self.button_login.pack()

Finally, let’s create an instance of the LoginForm class and start the Tkinter main loop to display the login form:

root = Tk()
login_form = LoginForm(root)
root.mainloop()

That’s it! You have successfully created a login form for apps using Python and Tkinter. In the next part of this tutorial, we will add more functionality to the login form such as error messages and registration options. Stay tuned for part 2!
