To efficiently generate personalized legal letters for each client, you will use Python's string formatting features. This approach allows you to insert client-specific details—such as name, case number, and a tailored message—directly into a letter template. Begin by defining a hardcoded list of client data, where each client is represented by a dictionary containing their name, case number, and message. You can iterate through this list using a `for` loop. For each client, use an f-string or the `.format()` method to create a letter that includes the relevant details. Then, assign the resulting letter to a variable whose name reflects the client's identity, such as `letter_john_smith` for a client named John Smith. This process ensures each letter is both personalized and accessible by a descriptive variable name.
