Use Python to connect and interact with a MySQL database. Write the program to perform the following task 

import mysql.connector

# Establish connection to the MySQL database
try:
    connection = mysql.connector.connect(
        host="localhost",  # Replace with your MySQL host
        user="root",        # Replace with your MySQL username
        password="password",  # Replace with your MySQL password
        database="Student"    # Replace with your database name
    )
    if connection.is_connected():
        print("Connected to the database successfully!")

    cursor = connection.cursor()

    # Display all records from the Students table
    query = "SELECT * FROM Students"
    cursor.execute(query)
    records = cursor.fetchall()
    print("\nAll Records:")
    for record in records:
        print(record)

    # Insert a new record into the Students table
    query = "INSERT INTO Students (StudentID, StudentName, Age, Class, Marks) VALUES (%s, %s, %s, %s, %s)"
    new_student = (6, "Fiona Adams", 16, "11th", 78)
    cursor.execute(query, new_student)
    connection.commit()
    print("\nNew record inserted successfully.")

    # Display all records after insertion
    query = "SELECT * FROM Students"
    cursor.execute(query)
    records = cursor.fetchall()
    print("\nAll Records After Insertion:")
    for record in records:
        print(record)

    # Update the marks of the student with StudentID = 5
    update_query = "UPDATE Students SET Marks = %s WHERE StudentID = %s"
    cursor.execute(update_query, (70, 5))
    connection.commit()
    print("\nMarks updated successfully for StudentID = 5.")

    # Fetch and display the updated record
    fetch_query = "SELECT * FROM Students WHERE StudentID = %s"
    cursor.execute(fetch_query, (5,))
    updated_record = cursor.fetchone()
    print("\nUpdated Record:")
    print(updated_record)

except mysql.connector.Error as err:
    print(f"Error: {err}")

finally:
    if connection.is_connected():
        cursor.close()
        connection.close()
        print("\nDatabase connection closed.")
