Read File Into Words

def read_file_into_words(filename: str) -> list[list[str]]:
    """Parse a text file into a 2D list of words, i.e.
        "This is an example file with
        multiple lines of text" becomes
        [["This", "is", "an", "example", "file", "with"],
        "multiple", "lines", "of", "text"].

    Args:
        filename (str): Path to text file.

    Returns:
        list[list[str]]: 2D list of string words.
    """
    with open(filename) as input_file:
        content = input_file.readlines()
    content = [word.strip() for word in content]
    return content

Read JSON File into Dict

import json

def read_json_file_into_dict(filename: str) -> dict:
    """Parse a JSON file into a dictionary.

    Args:
        filename (str): Path to JSON file.

    Returns:
        dict: Dictionary representation of JSON file contents.
    """
    with open(filename, "r", encoding="utf-8") as json_file:
        content = json.load(json_file)
    return content
