You will need to convert uppercase characters to lowercase and add an underscore before them.
Before proceeding to work on the list comprehension, you're going to give your function a return value. In this way you'll be able to check the output.
Use the return statement to return the list snake_cased_char_list from your function.
You should return the snake_cased_char_list list. Ensure the indentation is set correctly.
const transformedCode = code.replace(/\r/g, "");
const convert_to_snake_case = __helpers.python.getDef("\n" + transformedCode, "convert_to_snake_case");
const { function_body } = convert_to_snake_case;
assert.match(function_body, /return\s*snake_cased_char_list/);
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 = []
