How Can I Access SQL Query Results by Column Name in Python?

Accessing SQL Query Results by Column Name in Python

Python provides several options for retrieving SQL result column values using column names rather than column indices. This approach is particularly useful when dealing with large tables with numerous columns, as it eliminates the need for manual index calculation and enhances code readability.

One such solution is to employ the DictCursor class provided by the MySQLdb module. This cursor enables you to access column values directly by their names, similar to the Java construct mentioned in the question.

To illustrate, consider the following example:

import MySQLdb

# Connect to the database
conn = MySQLdb.connect(...)

# Create a cursor using DictCursor class
cursor = conn.cursor(MySQLdb.cursors.DictCursor)

# Execute the query
cursor.execute("SELECT name, category FROM animal")

# Fetch all rows as a list of dictionaries
result_set = cursor.fetchall()

# Iterate through the rows and print column values by name
for row in result_set:
    print("%s, %s" % (row["name"], row["category"]))

This approach allows you to access column values using the column name as the dictionary key, providing a more intuitive and efficient way of handling SQL results.
