A python Program I wrote today

I wrote this python program to accept inputs (student ID, name and address) and then save it in a database. In addition, various kinds of exceptions are handled in the process.

import sqlite3
import tkinter


# Setting up the database and creating a table
database_connection = sqlite3.connect("students.db")
database_cursor = database_connection.cursor()
try:
    database_cursor.execute("""CREATE TABLE student_info (STUDENT_ID VARCHAR(11) NOT NULL,
    NAME VARCHAR(50) NOT NULL,
    ADDRESS VARCHAR(20) NOT NULL,
    PRIMARY KEY(STUDENT_ID))""")
except:
    ""


# Creating the interface
root = tkinter.Tk()
# Setting the width and height of the interface
root.geometry("640x300")

# Setting the title of the interface
root.title("My Application")

# creating the id label and positioning it on the interface
id_label = tkinter.Label(text="Student ID",font="Arial 10 bold")
id_label.grid(row=0,column=0,padx=20,pady=20)

# creating the id box and positioning it on the interface
id_box = tkinter.Entry(font="Arial 10 normal")
id_box.grid(row=0,column=1)


# creating the name label and positioning it on the interface
name_label = tkinter.Label(text="Name",font="Arial 10 bold")
name_label.grid(row=1,column=0)

# creating the name box and positioning it on the interface
name_box = tkinter.Entry(font="Arial 10 normal")
name_box.grid(row=1,column=1)


# creating the address label and positioning it on the interface
address_label = tkinter.Label(text="Digital Address",font="Arial 10 bold")
address_label.grid(row=2,column=0,pady=20)

# creating the address box and positioning it on the interface
address_box = tkinter.Entry(font="Arial 10 normal")
address_box.grid(row=2,column=1)


def clear():
    error_label.config(text="")


# creating a function for Saving the info in the database
def save():
    student_id = id_box.get()
    name = name_box.get()
    address = address_box.get()
    if student_id:
        if name:
            if address:
                query = database_cursor.execute("""SELECT * FROM student_info WHERE                      
                STUDENT_ID=?""",(student_id,))
                data = query.fetchall()
                if not data:
                    print("no data")
                    if len(student_id)<=11:
                        if len(name)<=50:
                            if len(address)<=20:
                                print("in")
                                try:
                                    database_cursor.execute("""INSERT INTO student_info
