Learn Python List Comprehension By Building a Case Converter Program - Step 20

Tell us what’s happening:

I get the error that I should ''.join(snake_cased_char_list).strip('_') at the end of convert_to_snake_case() function.

But I believe that’s what I did.

Your code so far

def convert_to_snake_case(pascal_or_camel_cased_string):
    # snake_cased_char_list = []
    # 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 = [
        '_' + char.lower() if char.isupper()
        else char
        for char in pascal_or_camel_cased_string
    return ''.join(snake_cased_char_list).strip('_')
    ]

def main():
    print(convert_to_snake_case('aLongAndComplexString'))

if __name__ == '__main__':
    main()

It should be after the list, not inside it.
