change a json value with a Python 3.8 script

I want change one json value with a Python 3.8 script.

I know in Python, strings are immutable, so you can't change their characters in-place.

This helps my much: How to find and replace a part of a value in json file

TypeError: 'str' object does not support item assignment

TypeError: 'str' object does not support item assignment item['hotKey'] = "" TypeError: 'str' object does not support item assignment

Script: item['hotKey'] = "<f11>"

from pathlib import Path
import json
home = str(Path.home())
path = home + "/.config/autokey/data/Sample Scripts/"
jsonFilePath = home + "/.config/autokey/data/Sample Scripts/.run-run-lintalistAHK-all.json"
with open(jsonFilePath) as f:
    data = json.load(f)
for item in data['hotkey']:
    item['hotKey'] = "<f11>"  # item['hotKey'].replace('$home', item['id'])
with open(jsonFilePath, 'w') as f:
    json.dump(data, f)

json file

{
     "hotkey": {
         "hotKey": "<f12>"
     },
}
Solution

  • You need to add json['hotkey'] reference before:

    for item in data['hotkey']:
    data['hotkey'][item] = "<f11>"  # item['hotKey'].replace('$home', item['id'])

    My raw attempt:

    import json
j = '''
{
     "hotkey": {
         "hotKey": "<f12>"
     }
}
'''
data = json.loads(j)
for x in data['hotkey']:
  data['hotkey'][x] = '<f11>'
print(data)
