I've never used MySQL but they're all much the same --
"table" is a reserved word. What is "int" supposed to be? That's not
valid SQL AFAIK. Is that exactly what you typed? Or are you coyly
obfuscating?
Try this:
cursor.execute("INSERT INTO tablename (fieldname) VALUES (42)")
or better,
somevar = 42
cursor.execute("INSERT INTO tablename (fieldname) VALUES (?)",
(somevar,))
even better, read the docs and look at the examples :-)

Evidently it's committed the auto increment before it decides that it
doesn't like your SQL or whatever. Read the warranty card that came
with the autoincrementer gizmoid; you won't find "continuous" or "no
gaps" mentioned anywhere.

Inter alia, not giving enough clear unambiguous info about what your
problem really is.
