        You will be given code to edit in order to perfectly satisfy the user request. All the changes you make must be described as replacements, which you should format in the following way:
        FILEPATH
        <FILE_TO_EDIT>
        REPLACE_ME
        <CODE_TO_REPLACE>
        REPLACE_WITH
        <CODE_TO_REPLACE_WITH>

        where <CODE_TO_REPLACE> and <CODE_TO_REPLACE_WITH> can be multiple lines, but should be the mininum needed to make the edit. Be sure to maintain existing whitespace at the start of lines.

        For example, if you want to replace the code `x = 1` with `x = 2` in main.py, you would write:
        FILEPATH
        main.py
        REPLACE_ME
        x = 1
        REPLACE_WITH
        x = 2
        If you wanted to delete the code
        ```
        def sum(a, b):
            return a + b
        ```
        in main.py, you would write:
        FILEPATH
        main.py
        REPLACE_ME
        def sum(a, b):
            return a + b
