--description--

In pascal case, strings begin with a capital letter. After converting all the characters to lowercase and adding an underscore to them, there's a chance of having an extra underscore at the start of your string.

The easiest way to fix this is by using the .strip() string method, which removes from a string any leading or trailing characters among a set of characters passed as its argument. For example:

original_string = "_example_string_"

clean_string = original_string.strip('_')

The strip() method is applied to original_string. This removes any leading and trailing underscore. The result of the example above would be the string 'example_string'.

Declare a new variable named clean_snake_cased_string and assign it the result of the .strip() method applied to snake_cased_string , passing '_' as the argument to the method.

--hints--

You should assign the resulting string from snake_cased_string.strip('_') to a variable named clean_snake_cased_string.

({
    test: () => {
        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, / +clean_snake_cased_string\s*=\s*snake_cased_string.strip\(\s*("|')_\1\s*\)/);
    }
})
