Hello,

def do(s):
    L = []
    for x in s.split():
        if x in ('or','and'):
            L.append(x)    
        elif x == 'not' and L and L[-1] == 'and':
            L.append('not')
        else:
            L.append("'*%s*'" % x)
    return ' '.join(L)

I think that it is more readable, maybe not faster, elegant I don't know =)
print 'Yeahh it was my first post on the list.'

bye.
