9.8 LAB - Database programming with Python (SQLite) Complete the Python program to create a Horse table, insert one row, and display the row. The main program calls four functions: 1. create_connection () creates a connection to the database. 2. create_table() creates the Horse table. 3. insert_horse() inserts one row into Horse. 4. select_all_horses () outputs all Horse rows. Complete all four functions. Function parameters are described in the template. Do not modify the main program. The Horse table should have five columns, with the following names, data types, constraints, and values: The program output should be: Name ld Name Breed Data type integer text text double Height BirthDate text Constraints primary key, not null 1 All horses: (1, 'Babe', 'Quarter Horse', 15.3, '2015-02-10') Value 'Babe' 'Quarter horse' 15.3 '2015-02-10' This lab uses the SQLite database rather than MySQL. The Python API for SQLite is similar to MySQL Connector/Python. Consequently, the API is as described in the text, with a few exceptions: • Use the import library provided in the program template. • Create a connection object with the function sqlite3.connect(": memory:"). • Use the character ? instead of %s as a placeholder for query parameters. • Use data type text instead of char and varchar.
