MySQLdb.html):
To perform a query, you first need a cursor, and then you can execute
queries on it:
c=db.cursor()
max_price=5
c.execute("""SELECT spam, eggs, sausage FROM breakfast
WHERE price < %s""", (max_price,))
In this example, max_price=5 Why, then, use %s in the string? Because
MySQLdb will convert it to a SQL literal value, which is the string
'5'. When it's finished, the query will actually say, "...WHERE price
< 5".
