辞書をJSON配列に変換するときのTypeError

キーと値が文字列であるpython辞書を取り、それをJSON文字列に変換するにはどうすればよいですか。

これは私が今持っているものです：

import json

def create_simple_meeting(subject, startDate, endDate, location, body):
    info = dict()
    if(subject != ""):
        info["subject"] = subject
    if(startDate != ""):
        info["startDate"] = startDate
    if(endDate != ""):
        info["endDate"] = endDate
    if(body != ""):
        info["body"] = body
    if(location != ""):
        info["location"] = location
    print(json.dumps(dict))

create_simple_meeting("This is the subject of our meeting.","2014-05-29 11:00:00","2014-05-29 12:00:00", "Boca Raton", "We should definitely meet up, man")

そして、それは私にこのエラーを与えます

    print(json.dumps(dict))

dictの代わりにtypeオブジェクト、infoをシリアル化しようとしています。適切な変数をダンプします。

print(json.dumps(info))
