Save JSON file with Python

save-file.py

import json

def writeToJSONFile(path, fileName, data):
    filePathNameWExt = './' + path + '/' + fileName + '.json'
    with open(filePathNameWExt, 'w') as fp:
        json.dump(data, fp)


# Example
data = {}
data['key'] = 'value'

writeToJSONFile('./','file-name',data)
# './' represents the current directory so the directory save-file.py is in
# 'test' is my file name

why not use:
import os
os.path.join('.', path, filename + '.json')
This solution is more error proof than yours.

what if i wanted to add more data as to what it previously had?

@i-vers

what if i wanted to add more data as to what it previously had?

use the a file permission instead of w, so it would be

with open("file.txt", "w") as f:
    f.write("Hello ")

with open("file.txt", "a") as f:
    f.write("World!")

file.txt

Hello World!

Well, in the case you are dealing with json, you cant do that, so you would have to first read the file
and then rewrite it from scratch using the already read data

in that case it would be

# Save the file
import json

with open("out.json", "w") as f:
    json.dump(f, [1, 2, 3])

# r+ is for both reading and writing
with open("out.json", "r+") as f:
    existing_data = json.load(f)     #  load   [1, 2, 3]  from the file
    existing_data.extend([4, 5, 6])  #  add    [4, 5, 6]   to the loaded data
    json.dump(f, existing_data)     #   write  [1, 2, 3, 4, 5, 6]  to the file

out.json

[1, 2, 3, 4, 5, 6]
