Your code so far

def convert_to_snake_case(pascal_or_camel_cased_string):

    # for char in pascal_or_camel_cased_string:
    #     if char.isupper():
    #       converted_character = '_' + char.lower()
    #       snake_cased_char_list.append(converted_character)
    #     else:
    #         snake_cased_char_list.append(char)
    # snake_cased_string = ''.join(snake_cased_char_list)
    # clean_snake_cased_string = snake_cased_string.strip('_')

    # return clean_snake_cased_string

    snake_cased_char_list = []

Hi and welcome to the forum :wave:

snake_cased_char_list is a list of elements. You need to join the elements together into a string using join()

Example:

myTuple = ("John", "Peter", "Vicky")

x = "#".join(myTuple)

print(x)
