How do I json serialize tweet data I get from the tweepy api?

Question

I'm trying to get the text from tweets about a hashtag that can be input and then store them in a json file so that I can do stuff like count how many times a word is used in all the tweets.

I tried to cast tweet as a string with str(tweet) but that just gave a different error and I mostly just did it as a guess.

api = tweepy.API(auth)

def jsontweetdump(tweet):
  with open('tweet.json', 'w') as outfile:
    json.dump(tweet, outfile)

hashtag = input()

for tweet in tweepy.Cursor(api.search, hashtag, count=10).items():
  jsontweetdump(tweet)

I expected that this would store data from ten tweets based on the hashtag i put in in a json file but I'm getting these error messages.

Traceback (most recent call last):
