How to update key of dictionary inside a JSON file?

This is an example of what’s in my JSON file:

 "person1": {
        "name": "Henry",
        "email": "none",
        "friends_amt": {
            "male": 0,
            "female": 0
         }

How would I change the male’s key (which is 0) and add one using “+=” in python? I wan a command to update the key of male or female. I don’t want to CHANGE 0 into 1, but I want to “+=” to that 0 so that I can update it over an over again. Please help, I am working on a project, Thanks

I tried to use:

with open("people.json", "w") as f:
  data = json.load(f)

data["person1"]["friends_amt", "male"] += 1

but it obviously failed and I expected that because my json knowledge is low and I took a wild guess

Answer

You wanna use data["person1"]["friends_amt"]["male"] instead of with a comma :)

Since [‘friends_amt’] is a dictionary in itself, you would use the selector you did with [‘person1’] and [‘friends_amt’]

Hope this helps!
