How can I insert NULL data into MySQL database with Python?

I'm getting a weird error when inserting some data from a Python script to MySQL. It's basically related to a variable being blank that I am inserting. I take it that MySQL does not like blank variables but is there something else I can change it to so it works with my insert statement?

I can successfully use an IF statement to turn it to 0 if its blank but this may mess up some of the data analytics I plan to do in MySQL later. Is there a way to convert it to NULL or something so MySQL accepts it but doesn't add anything?

When using mysqldb and cursor.execute(), pass the value None, not "NULL":

value = None
cursor.execute("INSERT INTO table (`column1`) VALUES (%s)", (value,))
