Assigning mongodb array element in a variable in pymongo

Question

i am making a self-project for practice but i am stuck at a point. I am not able to store the value of an element of an array of mongodb in a variable.

server = pymongo.MongoClient(url)
pokemon_python = server.pokemon_python
gonestarter = pokemon_python.gonestarter


bulba_health = gonestarter.find_one({"stats":{"$elemMatch":{"health": 15}}}, {"stats":{"$elemMatch":{"health": 15}}})


bulba_health = str(bulba_health["stats"])
print(f"Health: {bulba_health}")

the result is printed as Health: [{'health': 15}]

but the result i want is that only gives me Health: 15

Does bulba_health["stats"][0]["health"] get the value you want? — rickhg12hs

Given your current python code, you can access the value you want with:

bulba_health["stats"][0]["health"]

bulba_health["stats"] retrieves the array values of the "stats" field:

[{"health": 15}, ...]

bulba_health["stats"][0] retrieves the first element in the array:

{"health": 15}

bulba_health["stats"][0]["health"] retrieves the value of the "health" field:
