To create a registration form using tkinter and connect it to a MySQL database, you can follow these steps:
Step 1: Import Required Modules
    import tkinter as tk
    import mysql.connector
Step 2: Create a Connection to MySQL Database
    mydb = mysql.connector.connect(
      host="localhost",
      user="yourusername",
      password="yourpassword",
      database="yourdatabase"
    )
Step 3: Create a Cursor Object
    mycursor = mydb.cursor()
Step 4: Create a Tkinter Window and Widgets
    window = tk.Tk()
    window.title("Registration Form")
    
    # Create Labels
    tk.Label(window, text="First Name").grid(row=0, column=0)
    tk.Label(window, text="Last Name").grid(row=1, column=0)
    tk.Label(window, text="Email").grid(row=2, column=0)
    tk.Label(window, text="Password").grid(row=3, column=0)
    
    # Create Entry Widgets
    first_name = tk.Entry(window)
    last_name = tk.Entry(window)
    email = tk.Entry(window)
    password = tk.Entry(window, show="*")
    
    # Position Entry Widgets
    first_name.grid(row=0, column=1)
    last_name.grid(row=1, column=1)
    email.grid(row=2, column=1)
    password.grid(row=3, column=1)
Step 5: Define a Function to Submit Data to MySQL Database
    def submit():
        sql = "INSERT INTO users (first_name, last_name, email, password) VALUES (%s, %s, %s, %s)"
        values = (first_name.get(), last_name.get(), email.get(), password.get())
        mycursor.execute(sql, values)
        mydb.commit()
        print("Data Submitted!")
Step 6: Create a Submit Button and Call the Submit Function
    submit_button = tk.Button(window, text="Submit", command=submit)
    submit_button.grid(row=4, column=1)
Step 7: Run the Tkinter Window
    window.mainloop()
Here is the complete code:
    import tkinter as tk
    import mysql.connector
    
    # Create Connection to MySQL Database
    mydb = mysql.connector.connect(
      host="localhost",
      user="yourusername",
      password="yourpassword",
      database="yourdatabase"
    )
    
    # Create Cursor Object
    mycursor = mydb.cursor()
    
    # Create Tkinter Window and Widgets
    window = tk.Tk()
    window.title("Registration Form")
    
    # Create Labels
    tk.Label(window, text="First Name").grid(row=0, column=0)
    tk.Label(window, text="Last Name").grid(row=1, column=0)
    tk.Label(window, text="Email").grid(row=2, column=0)
    tk.Label(window, text="Password").grid(row=3, column=0)
    
    # Create Entry Widgets
    first_name = tk.Entry(window)
    last_name = tk.Entry(window)
    email = tk.Entry(window)
    password = tk.Entry(window, show="*")
    
    # Position Entry Widgets
    first_name.grid(row=0, column=1)
    last_name.grid(row=1, column=1)
    email.grid(row=2, column=1)
    password.grid(row=3, column=1)
    
    # Submit Function
    def submit():
        sql = "INSERT INTO users (first_name, last_name, email, password) VALUES (%s, %s, %s, %s)"
        values = (first_name.get(), last_name.get(), email.get(), password.get())
        mycursor.execute(sql, values)
        mydb.commit()
        print("Data Submitted
