Inserting NULL Data into MySQL Using Python

Inserting blank variables into MySQL databases from Python scripts can trigger errors. MySQL does not recognize blank variables, unlike other programming languages. To resolve this issue and insert NULL values instead of blanks, follow the steps below:

When employing mysqldb and cursor.execute() methods, assign the value None rather than "NULL" to the variable being inserted.

<code class="python">value = None
cursor.execute("INSERT INTO table (`column1`) VALUES (%s)", (value,))</code>

By providing None as the value, you instruct MySQL to interpret the entry as a NULL value, preventing any data distortion that might arise from converting blank values to zeros.

This approach adheres to MySQL's data type conventions and ensures accurate data handling for subsequent analysis and processing.
