9.2.2 Method MySQLConnection.close()

Syntax:

cnx.close()

close() is a synonym for disconnect(). See Section 9.2.20, “Method MySQLConnection.disconnect()”.

For a connection obtained from a connection pool, close() does not actually close it but returns it to the pool and makes it available for subsequent connection requests. See Section 8.1, “Connector/Python Connection Pooling”.
