In Python’s SQLite module, the cursor object is used to execute SQL queries and fetch data from the database. It acts as a pointer to a specific location in the result set of a query, allowing you to iterate over the rows returned by the query and perform various operations on them.

Here’s how you can work with the cursor object in SQLite:

1. Creating a Cursor: To create a cursor object, you first need to establish a connection to the SQLite database using the `connect()` method, and then call the `cursor()` method on the connection object.

2. Executing Queries: Once you have a cursor object, you can use it to execute SQL queries using the `execute()` method. This method takes an SQL query as its argument and executes it against the database.

3. Fetching Data: After executing a query, you can fetch the results using methods like `fetchone()`, `fetchall()`, or `fetchmany()`. These methods allow you to retrieve one row, all rows, or a specified number of rows from the result set, respectively.

4. Iterating Over Results: You can iterate over the rows returned by a query using a `for` loop or a list comprehension. Each row fetched from the cursor represents a tuple of values corresponding to the columns in the result set.

5. Closing the Cursor: Once you’re done working with the cursor, it’s good practice to close it using the `close()` method. This releases any resources associated with the cursor and frees up memory.

Here’s a basic example demonstrating how to use the cursor object in SQLite:

“`python
import sqlite3

# Connect to the SQLite database
connection = sqlite3.connect(‘example.db’)

# Create a cursor object
cursor = connection.cursor()

# Execute a SQL query
cursor.execute(“SELECT * FROM example”)

# Fetch one row from the result set
row = cursor.fetchone()
print(row)

# Fetch all rows from the result set
rows = cursor.fetchall()
for row in rows:
print(row)

# Close the cursor and connection
cursor.close()
connection.close()
“`

In this example:

– We establish a connection to an SQLite database file named `example.db`.
– We create a cursor object using the `cursor()` method.
– We execute a SELECT query to retrieve all rows from the `example` table.
– We fetch one row using the `fetchone()` method and print it.
– We fetch all remaining rows using the `fetchall()` method and iterate over them, printing each row.
– Finally, we close the cursor and connection.
