When you want to automate the organization of legal documents in Python, you can start by using a hardcoded list of document names and their types. This means you define the data directly in your script, rather than reading it from a user or a file. To organize this data, you will build a dictionary where each key is a document type (such as `contract` or `memo`) and the value is a list of file names belonging to that type. After constructing this dictionary, you can display the results by printing the dictionary to the console. This approach helps you quickly see how your documents are grouped by type and can serve as a foundation for more advanced automation tasks.
