Tell us what’s happening:

List comprehensions accept conditional statements, to evaluate the provided expression only if certain conditions are met:

Example Code
spam = [i * 2 for i in iterable if i > 0]
As you can see from the output, the list of characters generated from pascal_or_camel_cased_string has been joined. Since the expression inside the list comprehension is evaluated for each character, the result is a lowercase string with all the characters separated by an underscore.

Follow the example above to add an

def convert_to_snake_case(pascal_or_camel_cased_string):

    # for char in pascal_or_camel_cased_string:

    #       converted_character = '_' + char.lower()
    #       snake_cased_char_list.append(converted_character)

    # snake_cased_string = ''.join(snake_cased_char_list)
