1. Write the Python code for creating a table based on the following SQL statement:
   • CREATE TABLE phone (
   • phone_id INT,
   • country_code INT NOT NULL,
   • phone_number INT NOT NULL,
   • phone_type VARCHAR(12),
   • PRIMARY KEY(phone_id)
   • );
2. Write the Python code to select rows from the table based on the following SQL statement:
   • SELECT phone_number
   • FROM phone
   • WHERE country_code = 'US'
3. Write the Python code to update rows in the table based on the following SQL statement:
   • UPDATE phone
   • SET phone_type = 'MOBILE
   • WHERE phone_type = 'CELLULAR'
4. Write the Python code to delete rows in the table based on the following SQL statement:
   • DELETE FROM phone
   • WHERE country_code = 'XX'
5. Write the Python code to drop the table based on the following SQL statement:
   • DROP TABLE phone
