Python: Transforming a MySQL Table to a List of Dictionary Objects Using mysqldb
In Python, the mysqldb module provides a means to connect to and interact with MySQL databases. This includes the ability to fetch data from tables and convert it into appropriate data structures.
One common use case is converting a MySQL table into a list of dictionary objects. This allows for easy manipulation and iteration over the data in Python. To achieve this, mysqldb offers a specialized cursor class known as the DictCursor.
To utilize the DictCursor, simply specify it as the cursor class when connecting to the database:
import MySQLdb.cursors connection = MySQLdb.connect(host='...', cursorclass=MySQLdb.cursors.DictCursor)
Once the connection is established, you can execute queries against the database. The resulting cursors will produce rows as dictionaries, making it straightforward to create a list of desired objects:
cursor = connection.cursor() query = 'SELECT * FROM my_table' cursor.execute(query) results = [row for row in cursor]
In this example, the results variable will contain a list of dictionaries, each representing a row from the MySQL table. The dictionary keys correspond to the column names, and the values are the respective cell values.
