Can someone tell me what's wrong with this Syntax?

>>>y = 14
>>> cursor.execute("INSERT INTO accounts VALUES ('Bobby', %s)", (y))
Traceback (most recent call last):

  File "/Library/Python/2.7/site-packages/mysql/connector/cursor.py", line 477, in execute

  File "/Library/Python/2.7/site-packages/mysql/connector/cursor.py", line 355, in

y should be inside a tuple:

cursor.execute("INSERT INTO accounts VALUES ('Bobby', %s)", (y, ))

FYI, (y) is not a tuple - it is an int in parenthesis, adding comma (y,) makes it a tuple with one element inside:

>>> y = 14
>>> type((y))
<type 'int'>
>>> type((y,))
<type 'tuple'>
