Introduction
Writing to a JSON file
Instruction
Bravo! Of course, we can modify data before we save it in the file. Have a look at our new data, which is in the posts dataset:
posts = [
{
"id": 1,
"body": "This animation has navigated right into my heart.",
"approved": false
},
...
]
We will choose only those posts that are not approved:
data = []
for post in posts:
if not post["approved"]:
data.append(post)
Then we will save the result to a file:
with open('posts.json', 'w') as outfile:
json.dump(data, outfile)
Exercise
Choose posts that have fewer than 50 characters, and save the results to a file named short_posts.json.
Note: To get a length of a string, pass it in as an argument to the len() function.
Stuck? Here's a hint!
data = []
for post in posts:
if len(post["body"]) < 50:
data.append(post)
