Python Iterate through dictionary, determine if given string matches any name value

I looked through this post trying to figure out how to find out if a given string matches a certain value in a dictionary, but it's throwing nothing back. I have a dictionary with dictionaries and I'm trying to figure out how I can, let's say if given a string 'warrior', look through the dictionary, go inside the sub dictionary, check the name key for the given string, and if it exists, return the class. This is my code.

classes.py

#import playerstats
from player import playerStats

def setClass(chosenClass):
    chosenClass = chosenClass.upper()
    #function from post
    """print ([key
              for key, value in classes.items()
              if value == chosenClass])"""
    #this returns nothing
    for key, value in classes.items():
        if value == chosenClass:
            print(classes[chosenClass][value])
    #also returns nothing
    for i in classes:
        if classes[i]["name"] == chosenClass:
            print('true')
             
#create classes
classes = {
    'WARRIOR': {
        #define name of class for reference
        'name': 'Warrior',
        #define description of class for reference
        'description': 'You were  born a protector. You grew up to bear a one-handed weapon and shield, born to prevent harm to others. A warrior is great with health, armor, and defense.',
        #define what the class can equip
        'gearWeight': ['Cloth', 'Leather', 'Mail', 'Plate'],
        #define stat modifiers
        'stats': {
            #increase, decrease, or leave alone stats from default
            'maxHealth': playerStats['maxHealth'],
            'stamina': playerStats['stamina'] * 1.25,
            'resil': playerStats['resil'] * 1.25,
            'armor': playerStats['armor'] * 1.35,
            'strength': playerStats['strength'] * 0.60,
            'agility': playerStats['agility'],
            'criticalChance': playerStats['criticalChance'],
            'spellPower': playerStats['spellPower'] * 0.40,
        }
    }
}

player.py

import random
import classes

#set starter gold variable
startGold = random.randint(25,215)*2.5
#begin player data for new slate
playerStats = {
    'currentHealth': int(100),
    'maxHealth': int(100),
    'stamina': int(10),
    'resil': int(2),
    'armor': int(20),
    'strength': int(15),
    'agility': int(10),
    'criticalChance': int(25),
    'spellPower': int(15),
    #set gold as random gold determined from before
    'gold': startGold,
    'name': {'first': 'New', 'last': 'Player'},
}

What can I do to have it search through the dictionary, and if chosenClass is an existing class dictionary, return true or return the dictionary?

....
    #this returns nothing
    for key, value in classes.items():
        if value == chosenClass:

I think you should be comparing the key to chosenClass, instead of the value in that loop. An easy troubleshooting tool is to print stuff to see what is happening

....
    #this returns nothing
    for key, value in classes.items():
        print('key:{}, value:{}, chosenClass:{}'.format(key, value, chosenClass)
        if value == chosenClass:

But maybe an easier way to do it is:

def setClass(chosenClass):
    chosenClass = chosenClass.upper()
    chosen = classes.get(chosenClass, False)
    return chosen
