How Can I Safely Escape Strings for MySQL Insertion in Python?

Escaping Strings for MySQL in Python

When dealing with complex strings in Python that need to be stored in a MySQL database, proper string escaping is crucial to ensure data integrity. This article explores a Python solution to escape strings for MySQL, addressing the limitations of using triple single or double quotes.

Python's Escape Function for MySQL

The MySQL-Python library provides a dedicated function for escaping strings: conn.escape_string(). This function takes a string as input and returns an escaped version suitable for MySQL insertions.

Example Usage:

To escape a string for MySQL using conn.escape_string(), follow these steps:

import MySQLdb

# Establish a connection to the MySQL database
conn = MySQLdb.connect(host="localhost", user="username", password="password", db="database_name")

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

# Define the string to be escaped
input_string = "'This is a test string with special characters'"

# Escape the string
escaped_string = conn.escape_string(input_string)

# Execute the SQL query with the escaped string
cursor.execute("INSERT INTO table_name (column_name) VALUES (%s)", (escaped_string,))

# Commit the changes to the database
conn.commit()
