Json file to csv in Python

If I use this script to convert from Json to Csv in Python:

import json

import csv

with open("data.json") as file:
    data = json.loads(file)

with open("data.csv", "w") as file:
    csv_file = csv.writer(file)
    for item in data:
        csv_file.writerow([item['studio'], item['title']] +    item['release_dates'].values())

It throws an error message:

Traceback (most recent call last):

File "<stdin>", line 2, in <module>

File "C:\Python27\lib\json\__init__.py", line 338, in loads
    return _default_decoder.decode(s)

File "C:\Python27\lib\json\decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
TypeError: expected string or buffer

You're using json.loads() when you should be using json.load().

json.loads is for reading from a string, whereas json.load is for reading from a file.

Visit here for more information: https://docs.python.org/2/library/json.html.

Also, unrelated, but you can chain with statements.

with open("data.json") as json_file, open("data.csv", "w") as csv_file:
    csv_file = csv.writer(csv_file)
    for item in json.load(json_file):
        csv_file.writerow(...)
