Python 3: Saving API Results into CSV - python-3.x

Question

I'm writing a script which requires a daily updated CSV source file which lists many movie details and have decided to use Python3 to create and update it even though I don't know too much about it.
I believe I've got the code down to pull the information via TheMovieDB.org's API that I need, but currently can only get it to echo the results and not save in a CSV. Below are a couple of questions I have, the code that I currently have, and an example of it's current output.
Questions:
1. What do I need to do add to get the resulting data into a CSV? I've tried many things but so far haven't gotten anything to work
2. What would I need to add so that rerunning the script would completely overwrite the CSV produced from the last run? (not append or error out)
3. Optional: Unless tedious or a pain, it would be nice to have a column for each of the values provided per title within the CSV.
Thanks!!
Current Code
import http.client
import requests
import csv
conn = http.client.HTTPSConnection("api.themoviedb.org")
payload = "{}"
conn.request("GET", "/3/discover/movie?page=20&include_video=false&include_adult=false&sort_by=primary_release_date.desc&language=en-US&api_key=XXXXXXXXXXXXXXXXXXXXXXXXXXX", payload)
res = conn.getresponse()
data = res.read()
print(data.decode("utf-8"))
Result That's Echoed from the above Current Code

Answer 1

import json
import http.client
import requests
import csv
conn = http.client.HTTPSConnection("api.themoviedb.org")
payload = "{}"
conn.request("GET", "/3/discover/movie?page=20&include_video=false&include_adult=false&sort_by=primary_release_date.desc&language=en-US&api_key=XXXXXXXXXXXXXXXXXXXXXXXXXXX", payload)
res = conn.getresponse()
data = res.read()
json_data = json.loads(data)
results=json_data["results"]
for item in results:
print (item('vote_count'))
#write code to get necessary objects to write in csv
This is a way how you can do it. Comment if you have any query.

Answer 2

That looks like a JSON object, so you can parse it into a python dictionary using:
import json
mydict = json.loads(data)
Probably the values you want are in mydict[results] which is another set of key:value pairs. Depending on how you want these you could use a CSV library or just iterate through them and the print the contents with a tab between them.
for item in vars["results"]:
for k in item:
print("{}\t{}".format(k,item.get(k)))
