Step 1

In this project, you are going to build a program that takes a `camelCase` or `PascalCase` formatted string as input and converts that to a `snake_case` formatted string using two approaches. First, you'll use a for loop and then list comprehension to achieve the same results. You'll see how list comprehension can make your code more concise. Start defining a new function named `convert_to_snake_case()` that accepts a string named `pascal_or_camel_cased_string` as input. For now, add a `pass` statement inside the function.
