How can I check if a string exists in a dictionary inside of a list in python?

September 3, 2023

So, I’m creating this simple battle system as a small project and at the end I need to check if the player has that monster in their team already, however I cannot seem to be able to check all of their team list at once.

Here is the details of the code (not the entire code just the basis for this problem):

monster1 = {
    "name": "monster1",
    "type": "Fire",
    "hp": 78,
    "atk": 52,
    "def": 43,
    "spAtk": 60,
    "spDef": 50,
    "spd": 65
}

monster2 = {
    "name": "monster2",
    "type": "Water",
    "hp": 82,
    "atk": 60,
    "def": 32,
    "spAtk": 48,
    "spDef": 60,
    "spd": 70
}

myteam = [monster1, monster2]
eMon = monster2

if eMon not in myteam:
   print("You Won! Would you like to capture this monster?")
   opt = input("y/n ")

I’ve tried using eMon[‘name’] instead, but it still gives the result as if it is not in the team even if it is.

any solution?

Thanks for the help, the code is now working as intended.

>Solution :

Solution:

I would gather the team names as strings then the rest of your code is basically the same. This seems to be the most simple way.

monster1 = {
    "name": "monster1",
    "type": "Fire",
    "hp": 78,
    "atk": 52,
    "def": 43,
    "spAtk": 60,
    "spDef": 50,
    "spd": 65
}

monster2 = {
    "name": "monster2",
    "type": "Water",
    "hp": 82,
    "atk": 60,
    "def": 32,
    "spAtk": 48,
    "spDef": 60,
    "spd": 70
}

my_team = [monster1, monster2]
my_team_names = [e_mon['name'] for e_mon in my_team]
e_mon = 'monster2'


if e_mon not in my_team_names:
   print("You Won! Would you like to capture this monster?")
   opt = input("y/n ")
