How to overcome TypeError: Object of type datetime is not JSON serializable

Question

PreFile :

PreFile = {
  "Preferences": {
    "Quotas": {
       "Rate limit": 0,
       "Reset time": "2020-10-28 10:57:21.482911"
       }
    }
  }

My code:

    PrefFile["Preferences"]["Quotas"]["Reset time"] = data_option
       with open(Preferences_Path, 'w') as Preferences_File:
           json.dump(PrefFile, Preferences_File, indent=4, sort_keys=True)

 
    PreResetTime = PreFile["Preferences"]["Quotas"]["Reset time"]
    ResetTime = datetime.strptime(PreResetTime, '%Y-%m-%d %H:%M:%S.%f')

Error output: TypeError: Object of type datetime is not JSON serializable

  File "main_functions.py", line 158, in updating_preferences
    json.dump(PrefFile, Preferences_File, indent=4, sort_keys=True)

I'm going to use ResetTime later in the program

if(ResetTime < (time_now - timedelta(hours=24))):
      code...

For this line:

PrefFile["Preferences"]["Quotas"]["Reset time"] = data_option

Change to this or similar:

PrefFile["Preferences"]["Quotas"]["Reset time"] = data_option.isoformat()

convert your data_option to string before updating PrefFile["Preferences"]["Quotas"]["Reset time"] Answer by @Shijith
