(1) Example:

THREE RANDOM LETTERS

def new_tag_letters():

    LETTERS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

    tag_letter_1 = random.choice(LETTERS)

    tag_letter_2 = random.choice(LETTERS)

    tag_letter_3 = random.choice(LETTERS)

    return tag_letter_1, tag_letter_2, tag_letter_3

---------------------------------------------------------------------------------------------

(2)  Example:

PREPARE A RANDOM NUMBER FOR SEED

random_number  = random.random()                   

0.7152380063066679                                                     # decimal number

 random_number = round(random_number,4)

0.7152                                                                                         #round decimal number to four digits

 random_number = random_number * 10000

7152                                                                                             #make into integer

---------------------------------------------------------------------------------------------

NUMBERS ARE LINKED TO UNIQUE SEED VALUES, SHARING THE SAME FORMAT

random.seed(7152)        #Load number first. The next random output is the seed value.

seed_output = random.random()
