Python - Add to json list via Python

Question

My json file

{
   "people": []
}

My python code

with open("people.json") as jsonFile:
    load = json.load(jsonFile)
    data = {
    "fname": "Jason",
    "lname": "Scott",
    "age": 32,
    "job": "web developer",
    "spouse": "Jane Scott"
    }

    load["people"].append(data)

jsonFile.close()

I want to add to the list from my python file, with my code above, the json file remains unchanged.

You haven't written anything back into the file. Open up the file in write mode (open("people.json", r+)), then after you append the data, you'll need to json.dump the new dictionary into the file.

Also, no need to do jsonFile.close() at the end. Your with statement deals with that.

when dumping the data, it does not add to the list, but rather the end of the file, any idea on a fix?
