Executing SQL Commands With Python

What is the primary focus of the lesson 'Executing SQL Commands With Python'?

• Learning advanced SQL commands

• Interacting with SQLite databases through Python scripts

• Understanding the history of SQL

• Using DB Browser for database management

Why is Python considered ideal for working with SQLite?

• It allows embedding SQL queries within Python code

• It is only used for web development

• It lacks extensive libraries

• It has a complex syntax

What is the purpose of the 'conn = sqlite3.connect('car_showroom.db')' line in a Python script?

• To fetch results from the database

• To close the database connection

• To establish a connection to the database

• To execute SQL commands

Which method is used to fetch all results from an executed SQL query in Python?

• cursor.fetchall()

• conn.commit()

• cursor.execute()

• conn.close()

What is the role of the cursor object in a Python script interacting with SQLite?

• It acts as an intermediary between the script and the database

• It is used to close the database connection

• It stores the database file

• It is used to print results to the console

How can you modify a SQL query to retrieve cars of a specific make, such as 'Toyota'?

• cursor.execute('SELECT * FROM inventory WHERE year = 2019')

• cursor.execute('SELECT * FROM inventory WHERE model = 'Toyota'')

• cursor.execute('SELECT * FROM inventory WHERE make = 'Toyota'')

• cursor.execute('SELECT * FROM inventory WHERE make = 'Ford'')

What is the benefit of using ? placeholders in SQL queries?

• To make the query more readable

• To prevent SQL injection vulnerabilities

• To increase the speed of query execution

• To allow the use of single quotes in queries

Why is it important to handle user input carefully when constructing dynamic queries?

• To make the script run faster

• To prevent the use of double quotes

• To ensure the input matches the database structure

• To avoid using the title() method

What method is used to convert user input to title case in Python?

• str.title()

• str.capitalize()

• str.lower()

• str.upper()

What is a potential enhancement for the dynamic query script mentioned in the lesson?

• Use only hardcoded queries

• Include additional search criteria

• Display results in a less readable format

• Remove all error handling
