You can use something like this

iabbrev <expr> class getline('.') ==# 'class' ? 'class (object):' : 'class'

The key moment here is "<expr>". The expression

getline('.') ==# 'class' ? 'class (object):' : 'class'

will be evaluated to obtain replacement string. You can make it more
accurate by comparison only with the part before the cursor position.
