[Regexes] Stripping puctuation from a text

[shabda raaj]

I want to strip punctuation from text.

So I am trying,

>>p = re.compile('[a-zA-Z0-9]+')
p.sub('', 'I love tomatoes!! hell yeah! ... Why?')

' !! ! ... ?'

Which gave me all the chars which I want to replace.

So Next I tried by negating the regex,

>>p = re.compile('^[a-zA-Z0-9]+')
p.sub('', 'I love tomatoes!! hell yeah! ... Why?')

' love tomatoes!! hell yeah! ... Why?'

But this removed the first char instead of the puctuation. So I guess
^ is matching start of line, instead of negation. How can I take
negation of the regex here?
