从具有多个返回值的函数中仅访问一个返回值

Question

I am having trouble figuring out how I would access a value returned from a function where I am returning multiple values. I have a dictionary object that contains a tuple for the values like this.

import random

payments = {'12345678121365489': ('11', '2022', '666'),
            '5136982546823120': ('03', '2021', '523')}

def pick_card_combo():
    rand_dict, info = random.choice(list(practice_dict.items()))
    return(rand_dict, info)

Of course, I can index the "info" tuple and pick out certain elements but I was wondering how I could get each individual index for my generator expression in this function here.

def create_accounts(accs_gend):
    my_gen = ([first_name(), last_name(), country, pick_card_combo()
               <rand_dict>, <info[0]>, <info[1]>, <info[2]>] for i in range(accs_gend))
    account = tuple(my_gen)
    print(account)

I have different items in that dictionary so I would like for the various items to be used with the different tuples I generate and not just one item. Is there a way to access each respective return value here why calling this function each time a new element is generated?

I prefer to keep my generator objects inside the tuple as is too since that is the format which xlsxwriter requires it.

break it down more

def create_account():
    """ create one single account """
    rand_dict, info = pick_card_combo()
    return ([first_name(), last_name(), country,]+ [rand_dict,] + info )

def create_accounts(accs_gend):
    """ Create some number of random accounts """
    for i in range(accs_gend):
        yield create_account() # by using yield this is a "generator" 

five_random_accounts = tuple(create_accounts(5)) # calling tuple will evaluate the generator and create a tuple of all the elements
