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

Tell us what’s happening:

Can someone help me by explaining the condition correctly. I get the input [‘_l _a _c _s’] but Im not sure if it is correct.

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


# User Editable Region

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

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

main()

you created a new line, so the tests fail as they are still checking the first line

Which exact line? Because I’m not sure if I have an extra line.

Welcome to the forum @Adam1234

Here you have an extra line of code.

Happy coding

Thanks so much! I completed the level after 2 days! I can’t describe how thankful I am to both of you.
