Tell us what’s happening:

it does’t approve my code
please help me what to do

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

# User Editable Region

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

# User Editable Region


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

main()

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

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

do you think the issue may be that you have three comprehensions? that’s two too many

@ILM

Welcome to the forum @rudra2008

So the forum can assist please post your full updated code.

Here are some instructions on how to post code.

When you enter a code block into a forum post, please precede it with three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add the backticks.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Happy coding
