The word not is used with do to make a verb negative, as in I don't have any money (don't = do not). No is used as an adjective in front of a noun, as in I have no money. Both of these examples are acceptable ways of expressing the idea that you do not have something.

Note these contracted negative forms with do:

I don't
you don't
he, she doesn't
they don't
we don't

Here are some affirmative words and their negative forms in English:

AFFIRMATIVES

someone, anybody
something, anything
still
ever
either... or

NEGATIVES

Avoid using more than one negative in a clause:

–I don't have any money.
  NOT: I don't have no money.

–They don't see anybody.
  NOT: They don't see nobody.

–I didn't do anything.
  NOT: I didn't do nothing.
