bottle-jsonp.py

# This will return either JSON or JSONP depending on the existence of a callback. 

def jsonp(request, dictionary):
    if (request.query.callback):
        return "%s(%s)" % (request.query.callback, dictionary)
    return dictionary

def something():

bottle-jsonp2.py

# If you want to add a slightly more appropriate content type for JSONP ("application/javascript") you can, 
# but it'll work either way

    return dictionary
