Relatively new to python, apologies if the question/script is verbose and vague. The script below returns the key and value of the team name searched (Ex: 2, Charlotte Hornets); however, I would also like it to return the league name it's in as well. Such as 'nfl', 'nba', 'mlb'; based on the dictionary it's found in (Ex: 2, Charlotte Hornets, nba). Been working on this for a while, but can't find a dynamic solution. Thanks for the help in advance!

NFL_Teams = {1: "Arizona Cardinals", 2: "Atlanta Falcons", 3: "Baltimore Ravens"}

NBA_Teams = {1:'Washington Wizards', 2:'Charlotte Hornets', 3: 'Atlanta Hawks'}

MLB_Teams = {1: 'Los Angeles Dogers', 2: 'Cincinnati Reds', 3: 'Toronto Blue Jays'}    



def Standings(reply):

    def dictionary_search(name, dictionary):

        for key, value in dictionary.items():

            if value == name:

                return True # Boolean to show if team name is in merged dictionaries. 

            if key == name:

                pass # Used as a throw-away variable



    for single_dictionary in (NFL_Teams, NBA_Teams, MLB_Teams):

        if dictionary_search(reply, single_dictionary):

            for key, value in single_dictionary.items():

                if reply == value:

                    print(key, value)

            break

    else:

        print('Please Try Again')



Standings('Charlotte Hornets')

Once you assign the dict to another var called 'single_dictionary', you actually lose the name.. So i tried to map between the league name to the original dict of teams.

Running on:

teams = {'NFL': {1: "Arizona Cardinals", 2: "Atlanta Falcons", 3: "Baltimore Ravens"},

         'NBA': {1:'Washington Wizards', 2:'Charlotte Hornets', 3: 'Atlanta Hawks'},

         'MLB': {1: 'Los Angeles Dogers', 2: 'Cincinnati Reds', 3: 'Toronto Blue Jays'}}



# NFL_Teams = {1: "Arizona Cardinals", 2: "Atlanta Falcons", 3: "Baltimore Ravens"}

# NBA_Teams = {1:'Washington Wizards', 2:'Charlotte Hornets', 3: 'Atlanta Hawks'}

# MLB_Teams = {1: 'Los Angeles Dogers', 2: 'Cincinnati Reds', 3: 'Toronto Blue Jays'}



def standings(reply):

    for league, single_dictionary in teams.items():

        if reply in single_dictionary.values():

            for key, value in single_dictionary.items():

                if reply == value:

                    print(key, value)

                    print(league)

            break

    else:

        print('Please Try Again')



standings('Charlotte Hornets')

Will print:

2 Charlotte Hornets

NBA

Are the numbers used as keys important?
Would it make sense to have read them into the dictionaries the other way around? - then you can use a try except KeyError statement. This might be preferable for very large dictionaries (though this won't be the case here for teams in a league). It also might be a more object orientated way of thinking: the team name is the object identifier, whilst (I presume the numbers are current league positions?) league position is a property (and a changeable one at that). So for example (adapting Aaron_ab's answer)

teams = {'NFL': {"Arizona Cardinals":1, "Atlanta Falcons":2, "Baltimore Ravens":3},

     'NBA': {'Washington Wizards':1, 'Charlotte Hornets':2, 'Atlanta Hawks':3},

     'MLB': {'Los Angeles Dogers':1, 'Cincinnati Reds':2, 'Toronto Blue Jays':3}}



def standings(team):

    for league, teams_dict in teams.items():

        try:

            teams_dict[team]

            print(teams_dict[team], team)

            print(league)

            break

        except KeyError:

            continue   

Alternatively, drop the numbers and have a dictionary of lists (where the order of the list is the current league order):

import numpy as np



teams = {'NFL': ["Arizona Cardinals", "Atlanta Falcons", "Baltimore Ravens"],

     'NBA': ['Washington Wizards', 'Charlotte Hornets', 'Atlanta Hawks'],

     'MLB': ['Los Angeles Dogers', 'Cincinnati Reds', 'Toronto Blue Jays']}



def standings(team):

    for league, teams_list in teams.items():

        if team in teams_list:

            print(team, np.where(np.array(teams_list)==team)[0])

            print(league)
