i have this SQL

default code is a string

cr.execute(
                    '''SELECT product FROM product_product
                       WHERE default_code = '%s' limit 1'''

                        f"SELECT id FROM product_supplierinfo"
                        f" WHERE product_tmpl_id = {str(product_tmpl)}"

It is recommended to set the queries this way:

query = """Update employee set Salary = %s where id = %s"""
tuple1 = (8000, 5)
cursor.execute(query, tuple1)
