Dict has no attribute write() on json

Question

AttributeError: 'dict' object has no attribute 'write'

It happens on json.dump(data, config_file, indent=4)

import json


def get_json(path):
    with open(path, 'r') as f:
        return json.load(f)


def write_json(path, data):
    config_file = get_json(path)
    json.dump(data, config_file, indent=4)
    config_file.close()



def lines_to_dict(linesUp):
    lines = []
    for line in linesUp:
        lines.append(line.split(':'))
    return dict(lines)

I dont understand why i have an error like this? How can i modify this code?

TraceBack :

You need to open new file to write

Here is the example:

import json

def get_json(path):
    with open(path, 'r') as f:
        return json.load(f)

def write_json(path, data):
    with open(path, 'w', encoding='utf-8') as config_file:
        json.dump(data, config_file, indent=4)

if __name__ == '__main__':
    data = get_json('input.json')
    write_json('output.json', data)

Take a look at line:

with open(path, 'w', encoding='utf-8') as config_file:
