#list(set(...)) converts the combined set back into a list. This step is necessary because random.choice() expects a sequence (like a list) as its argument.
#Finally, c = random.choice(...) selects a random character from the combined list of characters.

##The join() method is used to concatenate the characters in the list l into a single string.
##The empty string '' is used as the separator between the characters. This means that each character in the list will be joined together without any spaces or other characters in between.
