Tell us what’s happening:

im pretty sure my code is mostly right but i cant find what the issue is.

Traceback (most recent call last):
File “main.py”, line 20, in
File “main.py”, line 18, in main
File “main.py”, line 14, in convert_to_snake_case
NameError: name ‘pascal_camel_cased_string’ is not defined

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


# User Editable Region

    snake_cased_char_list = ['_' + char.lower() if char.isupper() else char for char in pascal_camel_cased_string]

# User Editable Region

    return ''.join(snake_cased_char_list).strip('_')

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

main()
