将元组添加到嵌套字典中的列表

Question

I would like to add a tuple to a list for data that I already have in a nested dictionary format if it is missing.

all_cap = {"cap_1":{"id":1001, "vitals":[("Temp", 101), ("HR", 60)]}, "cap_2": 
{"id":1002, "vitals":[("Temp", 104), ("HR", 60), ("RR", 12)]}}

So, if I went to add a tuple ("RR", 16) to cap_1 it would work, but if I wanted to add it to cap_2 it would not overwrite the RR that is already there or even add the second RR to it. I've tried going in to it like this:

def add_vital(dict, str, int):
  if all_cap[dict]["vitals"][0][0:len("vitals")] == str:
    return True
  else:
    all_caps[dict]["vitals"].append(str, int)
    return False

I know that I have been asking quite a few questions on here today, and I truly do appreciate the answers I have received. It has been helping, but I just started trying to do some work in Python today (before now, I have only used R), so getting up and running with some of it has been daunting.

You can do this with lists of tuples by searching over them, but based on usage it really seems like these should just be dicts of dicts.

all_cap = { 
    "cap_1": { "id": 1001, "vitals": {
        "Temp": 101, 
        "HR": 60,
    }},
    "cap_2": { "id": 1002, "vitals": {
        "Temp": 104,
        "HR": 60,
        "RR": 12,
    }},
}

Now your add_vital function is just:

def add_vital(cap_id, vital, value):
    # type: (str, str, int) -> bool
    if vital in all_cap[cap_id]["vitals"]:
        return True
    else:
        all_cap[cap_id]["vitals"][vital] = value
        return False

Given the structure you've got, I think you need something more like:

def add_vital(cap_id, vital, value):
    # type: (str, str, int) -> bool
    if any([vital_pair[0] == vital 
            for vital_pair in all_cap[cap_id]["vitals"]]):
        return True
    else:
        all_cap[cap_id]["vitals"].append((vital, value))
        return False
