        "What we need to do is to create a template for a movie and record all the data that needs to go into that template. Data like title and storyline as well as functions like `show_trailer()` and `show_info()`.\n",

        "And then simply say that Avengers is a movie and similarly iron man is a movie. and then have the ability to say show me Iron Man trailer or show me details of Avengers, with no arguments necessary. Now this is someting that we are going to study next under OOPS ie. classes etc.\n",

        "But what if we still want to do it using only functions is to take a template that we have defined and make multiple copies of it.\n",

        "so we will have to make:\n",
        "\n",
        "1> avengers.py\n",

        "```\n",

        "  # Print movie information\n",
        "```\n",

        "- after we have done this for each and every movie we will can then call the functions to play their trailer or show their info.\n",
        "\n",
        "- what if we want to rename our functions or add more data for each movie we will have to edit each and every python files that are present for each movie. This is not a smart work.\n",
        "\n",
        "> so at the end of the day what we need is a way to make copies of a template without making multiple files. We can just create a template and just say that Avengers is a type of that template. And this new template is what we call as a class. We will be learning more about classes in the next module."
