Check a subkey value using a random variable and a condition. KeyError: "x"

Question

I’m having trouble with the dictionary code for checking the value of a subkey.

I want to get that:

If random_data is a word that matches "gender": "male" then I want to print "Word is Male"
If random_data is a word that matches "gender": "female", then I want to print "Word is Female"

I think the problem is the row if random_data == data["gender"]["male"], so I get the error:

KeyError: "gender"

How to fix?

import random

data = {

    #MALE
    "escritorio": {
        "gender": "male",
    },

    "viento": {
        "gender": "male",
    },

    #FEMALE
    "silla": {
        "gender": "female",
    },

    "mesa": {
        "gender": "female",
    },
    
}

#random key: escritorio or viento or silla or mesa
random_data =  random.choice(list(data))

if random_data == data["gender"]["male"]:
    print(random_data, ": word is Male")
else:
    print(random_data, ": word is Female")

KeyError: "gender"

"gender" is a nested key – i.e., it’s not in data.keys() ^{['escritorio', 'viento', 'silla', 'mesa']}, and "male" is not a key anywhere at all [it’s a value paired to "gender"]. What you want is probably something like:

if data[random_data]["gender"] == "male":
    print(random_data, ": word is Male")
else:
    print(random_data, ": word is Female")

or, using the ternary operator:

print(random_data, ": word is", "Male" if data[random_data]["gender"]=="male" else "Female")

You actually don’t even need conditions though – you can just have

print(random_data, ": word is", data[random_data]["gender"].capitalize())

Answer 2

The problem is that the value, "gender", is not a dictionary containing either "male" or "female".

This may work:

if data[random_data]["gender"] == "male":
    print(f"{random_data}: word is Male")
else:
    print(f"{random_data}: word is Female")
